documentation/mobile-manual: create a merged v3 manual

Unintentionally two versions of the mobile manual were created. This brings all of Willem's changes into the version for Subsurface-mobile v3, and restores the last version of the v2 mobile manual. This commit was manually created from a pull request that was signed off by Willem, given that he wrote most of the text I am copying that SOB into this commit and will assign authorship to him. To avoid further confusion, we now have a v2 and a v3 manual, explicitly named. The corresponding .html.git files were also updated (reflecting our switch to asciidoctor).

+<p>Welcome as a user of <em>Subsurface</em> and <em>Subsurface-mobile</em>, advanced dive logging
+software with extensive infrastructure to describe, organize, and interpret scuba
+and free dives. <em>Subsurface</em> offers many advantages over other similar
+software solutions, including compatibility with Windows, macOS, Linux (many
+distributions), Android and iOS. In addition, <em>Subsurface</em> is
+open-source software that allows downloading dive
+information from many dive computers.</p>
+</div>
+<div class="sect1">
+<h2 id="_introducing_subsurface_mobile">1. Introducing Subsurface-mobile</h2>
+<div class="sectionbody">
+<div class="paragraph">
+<p><em>Subsurface-mobile</em> is a limited mobile version of <em>Subsurface</em>
+aimed at Android and iOS smartphone and tablet devices, allowing viewing, entering, sharing, and storage of dive information at dive sites where a desktop
+computer is not useful. While the desktop version of <em>Subsurface</em> shows much more detailed information
+for each dive, the mobile version allows a more accessible dive log
+on a dive trip, useful for proving dive experience to dive shops or to review
+previous dives. <em>Subsurface-mobile</em> also allows
+the gathering of GPS locations where dives are performed.</p>
+</div>
+<div class="paragraph">
+<p>Users of <em>Subsurface-mobile</em> typically use the
+mobile app as a companion to the laptop/desktop version of <em>Subsurface</em>,  sharing dive information
+between the mobile and the desktop versions. However <em>Subsurface-mobile</em> can
+also be used independently of the desktop version and does not require the use of
+cloud storage.</p>
+</div>
+<div class="paragraph">
+<p><em>Subsurface-mobile</em> allows:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>Download and storage of dive log information using the <em>Subsurface</em> cloud.</p>
+</li>
+<li>
+<p>Viewing this information on a mobile device.</p>
+</li>
+<li>
+<p>Manually creating and adding new dive records to your dive log.</p>
+</li>
+<li>
+<p>Download dive data directly from many dive computers.</p>
+</li>
+<li>
+<p>Editing many of the dive log data fields, e.g. dive-master, buddy,
+equipment or notes relating to a dive.</p>
+</li>
+<li>
+<p>Recording, storing and applying GPS positions of dives.</p>
+</li>
+<li>
+<p>Viewing the localities of recorded GPS positions and of dives
+on a map.</p>
+</li>
+</ul>
+</div>
+<div class="paragraph">
+<p>These items are discussed in greater detail in the following text.
+<em>Subsurface-mobile</em> does not support download of dive data from all the
+dive computers that the desktop/laptop version can. This limitation is
+mainly caused by the inability of accessing some types of devices on the
+two mobile platforms. On Android, a subset of
+dive computers that use a FTDI USB interface or a Bluetooth / Bluetooth LE interface
+are accessible by <em>Subsurface-mobile</em>. On iOS, only Bluetooth LE based
+dive computers are supported.</p>

+<div class="paragraph">
+<p>Tap the "No cloud mode" button. The app will not access the <em>Subsurface</em>
+cloud storage server
+to obtain dive log information. This means that dive log information is
+stored on the mobile device only. If no dives have been entered into the dive log

+<h3 id="_using_cloud_storage">3.2. Using Cloud Storage</h3>
+<div class="paragraph">
+<p>The <em>Subsurface</em> developers provide a dedicated and
+free Internet cloud storage account that can be used for
+storing dive log information. This account can be created either from <em>Subsurface</em> on the desktop or from <em>Subsurface-mobile</em>
+using a mobile device; you can
+do full maintenance of a dive log from <em>Subsurface-mobile</em> alone. By using the same
+credentials with <em>Subsurface-mobile</em> and <em>Subsurface</em> for desktop, the <em>Subsurface</em> cloud storage allows sharing of a dive
+log between both (or even more than two) devices.</p>
+</div>
+<div class="paragraph">
+<p>The dive data on the cloud are cached locally both on the mobile device as well as on the desktop - it is easy to create backups of the data (for example in XML format) on the desktop: both mobile device and desktop keep a local copy of the data so that the dive log is always accessible, even without Internet connection. The Subsurface team never accesses a user&#8217;s dive data without explicit permission to do so, the data are not used for any purpose other than providing them to the user who created them. There are no ads and no harvesting / analysis of the data stored in the Subsurface cloud storage.</p>
+</div>
+<div class="paragraph">
+<p>1) Enter an e-mail address and a password in the fields indicated on the screen (see image above).
+The e-mail address should be in lower case and the password should contain a combination of
+letters from the alphabet (upper and lower case) and/or numbers.
+Tap the "Sign-in or Register" button. If you have already set
+up an account from the <em>Subsurface</em> desktop application, enter the same credentials here.
+Once the dive
+list has been downloaded from the cloud, <em>Subsurface-mobile</em> usually works only with the the local
+copy on the mobile device. This avoids long delays or even failure of operations if there is a bad (or no) internet connection, a situation fairly common at many dive sites. Once registered, <em>Subsurface-mobile</em> remembers the cloud credentials and it is not necessary to provide these again when launching the program.</p>
+</div>
+<div class="paragraph">
+<p>2) If this is a new cloud account, a PIN screen will open (see image on right, above). A PIN is e-mailed
+to the email address entered in the previous step. Enter this PIN into the field indicated
+and tap the <em>Register</em> button. The user
+information is stored on the cloud server and access to the cloud is enabled. In this case

+notification briefly appears on the screen. Now long-press the dive into which the copied information
+needs to be pasted. The same three icons appear on the target dive. Select the middle icon. A "Paste"
+notification briefly appears on the screen. This completes the copy-and-paste action. Continue by
+reviewing this new (pasted) information by manually editing the target dive.

-<div class="paragraph"><p><span class="blue"><em>Version 2, December 2017</em></span></p></div>
-<div class="paragraph"><p>Welcome as a user of <em>Subsurface</em> and <em>Subsurface-mobile</em>, advanced dive logging
-software with extensive infrastructure to describe, organize, and interpret scuba
-and free dives. <em>Subsurface</em> offers many advantages over other similar
-software solutions, including compatibility with Windows, macOS, Linux (many
-distributions), Android and iOS. In addition, <em>Subsurface</em> is
-open-source software that allows downloading dive
-information from many dive computers.</p></div>
-<div class="sect1">
-<h2 id="_introducing_subsurface_mobile">1. Introducing Subsurface-mobile</h2>
-<div class="sectionbody">
-<div class="paragraph"><p><em>Subsurface-mobile</em> is a more limited mobile version of <em>Subsurface</em>
-aimed at Android and iOS smartphone and tablet devices, allowing viewing, entering, sharing, and storage of dive information at dive sites where a larger
-computer is not useful. While the desktop version of <em>Subsurface</em> shows much more detailed information
-for each dive, the mobile version allows a more accessible dive log
-on a dive trip, useful for proving dive experience to dive shops or to review
-previous dives. <em>Subsurface-mobile</em> also allows
-the gathering of GPS locations where dives are performed.</p></div>
-<div class="paragraph"><p>Users of <em>Subsurface-mobile</em> typically use the
-mobile app as a companion to the laptop/desktop version of <em>Subsurface</em>,  sharing dive information
-between the mobile and the desktop versions. However <em>Subsurface-mobile</em> can
-also be used independently of the desktop version and does not require the use of
-cloud storage.</p></div>
-<div class="paragraph"><p><em>Subsurface-mobile</em> allows:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Download and storage of dive log information using the <em>Subsurface</em> cloud.
-</p>
-</li>
-<li>
-<p>
-Viewing this information on a mobile device.
-</p>
-</li>
-<li>
-<p>
-Manually creating and adding new dive records to your dive log.
-</p>
-</li>
-<li>
-<p>
-Download dive data directly from many dive computers.
-</p>
-</li>
-<li>
-<p>
-Editing many of the dive log data fields, e.g. divemaster, buddy,
-  equipment or notes relating to a dive.
-</p>
-</li>
-<li>
-<p>
-Recording, storing and applying GPS positions of dives.
-</p>
-</li>
-<li>
-<p>
-Viewing the localities of recorded GPS positions and of dives
-  on a map.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>These items are discussed in greater detail in the following text.
-<em>Subsurface-mobile</em> does not support download of dive data from all the
-dive computers that the desktop/laptop version can. This limitation is
-mainly caused by the ability to access different type of devices on the
-two mobile platforms. On Android, a subset of
-dive computers that use a FTDI USB interface or a Bluetooth / Bluetooth LE interface
-are accessible by <em>Subsurface-mobile</em>. On iOS, only Bluetooth LE based
-dive computers are supported.</p></div>

-<div class="sectionbody">
-<div class="paragraph"><p>When you start <em>Subsurface-mobile</em> for the first time, a Subsurface
-splash screen is shown while the program loads. On some devices this
-may take several seconds. After loading, the <em>Cloud Credentials screen</em> appears
-(see image below on left).</p></div>

-</div>
-</div>
-<div class="sect2">
-<h3 id="_when_not_using_cloud_storage">3.1. When NOT Using Cloud Storage</h3>
-<div class="paragraph"><p>Tap the "No cloud mode" button. The app will not access the <em>Subsurface</em>
-cloud storage server
-to obtain dive log information. This means that dive log information is
-stored on the mobile device only. If no dives have been entered into the dive log
-yet (the usual case), an empty dive log is created.</p></div>
-</div>
-<div class="sect2">
-<h3 id="_using_cloud_storage">3.2. Using Cloud Storage</h3>
-<div class="paragraph"><p>The <em>Subsurface</em> developers provide a custom
-free Internet cloud storage account that can be used for
-storing dive log information. This cloud storage account can be created either from <em>Subsurface</em> on the desktop or <em>Subsurface-mobile</em>
-using a mobile device; you can
-do full maintenance of a dive log from <em>Subsurface-mobile</em> alone. By using the same
-credentials wirh <em>Subsurface-mobile</em> and <em>Subsurface</em> for desktop, the <em>Subsurface</em> cloud storage allows you to share your dive
-log between both (or even more than two) devices.</p></div>
-<div class="paragraph"><p>The dive data are cached both on the mobile device as well as on the desktop - it is easy to create backups of the data (for example in XML format) on the desktop, and both mobile device and desktop keep a local copy of the data so that the dive log is always accessible, even without Internet connection. The Subsurface team never accesses a user&#8217;s dive data without explicit permission to do so, the data are not used for any purpose other than providing them to the user who created them. There are no ads and no harvesting / analysis of the data stored in the Subsurface cloud storage.</p></div>
-<div class="paragraph"><p>1) Enter an e-mail address and a password in the fields indicated on the screen.
-The e-mail address should be in lower case and the password should contain a combination of
-letters from the alphabet (upper and lower case) and/or numbers.
-Tap the "Sign-in or Register" button. If you have already set
-up an account from the <em>Subsurface</em> desktop application, enter the same credentials here.
-Once the dive
-list has been downloaded from the cloud, <em>Subsurface-mobile</em> usually works only with the the local
-copy on the mobile device. This avoids long delays or even failure of operations if there is a bad (or no) internet connection, a situation fairly common at many dive sites.</p></div>
-<div class="paragraph"><p>3) If this is a new account, a PIN screen will open (see image on right, above). A PIN is e-mailed
-to the email address entered in the previous step. Enter this PIN into the field indicated
-and tap the <em>Register</em> button. The user
-information is stored on the cloud server and access to the cloud is enabled. In this case
-the dive list is initially empty. Start entering dives in the dive
-log or download dive information from a supported dive computer.</p></div>
-<div class="paragraph"><p>The dive log can be updated automatically. If there is Internet connectivity, <em>Subsurface-mobile</em> accesses
-the cloud-based dive log to verify that the local copy of the dive log is still the
-same as the log in the cloud server. If not, the local copy and the copy on
-the server are synchronized.</p></div>

-<div class="sectionbody">
-<div class="paragraph"><p>At the bottom of many Subsurface-mobile screens is a round button that provides for
-several actions (see image below). The most common choice is indicated in a round colored <em>action button</em> (in the case below, edit a dive). Alternative actions are indicated in a white <em>action bar</em>.
-On Android devices, use the Android Back
-button for "cancel", "discard" or "back" actions. For example, when
-editing dive information, tapping the action button saves the changes while the
-Android back button can be used to cancel the edit without saving changes.</p></div>
-<div class="paragraph"><p>On iOS devices, on screens where a "back" action is enabled, a back arrow

-a message appears at the bottom of the screen, indicating that the cloud is
-being accessed, after which the dive list is shown. Once the list is loaded you can scroll up and down
-through your dive history.
-To upload dives from a dive computer, tap the blue action button. If you wish
-to add a dive manually, tap the + button in the action bar (described below).
-Tapping an existing dive on the list brings up a display of <em>Details View</em> for that dive
-(see image on right below). This includes the dive profile as well as

-<h2 id="S_Download">9. Download dives from a dive computer</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>The download deature supports only a limited number of dive computers. On
-Android devices these are typically dive computers using an FTDI interface
-using a USB OTG cable (but this is blocked on some Android devices by OS
-settings). Android devices also support all Bluetooth dive computers that
-are supported in Subsurface. And both Android and iOS devices allow direct
-download of dive data from a hand full of Bluetooth LE enabled dive
-computers.</p></div>
-<div class="paragraph"><p>Use the <em>Vendor name</em> and <em>Dive Computer</em> drop-downs to pick the correct
-dive computer. When downloading from multiple different dive computers, shortcut
-buttons to easily switch between them will appear below the drop-downs.</p></div>
-<div class="paragraph"><p>The process for download is slightly different between the two OSs.
-In our testing we got the best results on iOS when the dive computer was
-in Bluetooth mode before <em>Subsurface-mobile</em> is started. On most dive
-computers this is done through a menu entry, others (like the Suunto
-models) always respond to BLE requests.</p></div>
-<div class="paragraph"><p>On Android devices, you should first establish a link between the
-Bluetooth or Bluetooth LE dive computer and the mobile device using
-Android utilities. See below for more details.</p></div>
-<div class="paragraph"><p>For USB dive computers, USB cables "normally" used
-for uploading dives to a desktop/laptop computer do NOT work: these cables usually have a full-sized ("Type A") male USB plug
-on one end which plugs into the USB port of a desktop/laptop computer. For downloads to a mobile device
-one needs a USB OTG (USB On-The-Go) cable. In most cases it is required to plug the USB
-cable "normally" used with the dive computer into a USB OTG cable which, in turn, plugs into the mini-USB (or sometimes a USB "Type C")
-receptacle of the mobile device. The
-OTG cable usually has a full-size ("Type A") female receptacle at one end which accommodates the full-sized male plug
-of the USB cable "normally" used (see image below). This means that two cables are used to connect the dive computer to the mobile device.</p></div>
-<div class="paragraph"><p>Please note that not all Android devices support OTG cables. And even on some devices that do support those cables in general, <em>Subsurface-mobile</em> still in some cases cannot access a dive computer through a serial port.</p></div>
-<div class="imageblock" style="text-align:center;">
-<div class="content">
-<img src="mobile-images/USB-OTG.jpg" alt="FIGURE: USB-OTG cable" />
-</div>
-</div>
-<div class="paragraph"><p>For Bluetooth-equipped dive computers and Android devices, establish a Bluetooth connection between the dive computer and the
-mobile device. Use the tools on the mobile device to achieve pairing between the Bluetooth dice computer
-and the mobile device. For of Android devices,
-the Settings &#8594; Bluetooth tool is probably appropriate. Ensure pairing of the dive computer and mobile device.
-<em>Subsurface-mobile</em> performs communication using both Bluetooth and Bluetooth-low-energy (BTLE).
-The appropriate choice of Bluetooth communication is made by the software and the user need not be concerned with this.</p></div>
-<div class="paragraph"><p>With pairing between dive computer and <em>Subsurface-mobile</em> having been set up, dive download is simple.
-From the main menu, tap <em>Manage dives &#8594;  Download from DC</em>. A screen is shown requiring that the user specify
-the names of the vendor and model of the dive computer. For instance, when using a Shearwater Petrel 2 dive
-computer, the vendor is <em>Shearwater</em> and the Dive computer name is <em>Petrel 2</em>. From the two dropdown lists
-at the top of the screen, select the correct vendor and dive computer names (see image on the left, below).</p></div>
-<div class="paragraph"><p>Now tap the button labeled <em>Download</em>. The downloaded dives appear in the bottom part of the screen, the
-most recent dive at the top (see image on right, below). Be patient because the download can take a few minutes.
-As a matter of fact, a complete first download from some dive computers has been shown to take 45 minutes and longer.</p></div>
-<div class="paragraph"><p>After the download, each dive has a check-box on the left hand side, used for selecting which dives you want to be added to the
-<em>Subsurface-mobile</em> dive list: dives that are not checked are ignored. With the appropriate downloaded dives
-having been checked, tap the button at the bottom left labeled <em>Accept</em>. All the selected dives appear on
-the <em>Subsurface-mobile</em> dive list. The downloaded dive information can now be edited as described in the section

-You can choose to always sync with the cloud servers after every
-modification of the dive list. This is not recommended unless you are in
-an area with fast and reliable internet connection, as otherwise
-<em>Subsurface-mobile</em> might appear to hang between operations as it tries to
-connect to the cloud server. Selecting <em>Enable cloud auto sync</em> causes
-the local dive log to be synchronized with the copy in the cloud every time that
-<em>Subsurface-mobile</em> is closed. This option is a switch that allows auto
-sync to be either activated or to be switched off.</p></div>

-<div class="sectionbody">
-<div class="paragraph"><p>The fact that most smartphones have GPS facilities allows
-<em>Subsurface-mobile</em> to record
-the locations of dives. If the smartphone is taken on the dive boat
-during a dive, locations will be automatically recorded at regular intervals.
-These locations can then be applied to dives in the dive list. Here is how it&#8217;s done:</p></div>

-<h3 id="S_ConfigureGPS">12.1. Configuring the GPS service</h3>
-<div class="paragraph"><p>From the Main menu, select <em>Settings</em>. The Settings screen has a section for
-configuring the GPS service (image below). GPS location data
-are collected at regular intervals, e.g. every 5 minutes, or at regular
-distances, e.g. after the boat has moved more than 200m, or a combination of
-both of these approaches. Provide the appropriate information and
-tap the <em>Back</em> button. The program is now ready to collect GPS positions.</p></div>
