Start the iOS cross compile

The build.sh and readme files are the same as the Android ones
and I'll be changing them over time.

The configure-for-ios.sh script is a file that manages to set
everything, compilers frameworks and such, for iOS compilation.

I'll probably dissecate the configure-for-ios.sh file and put it
back on the build.sh, but not now.

+Tool repo to crosscompile subsurface to android-arm
+---------------------------------------------------
+
+Dependencies:
+
+1. android_sdk, android_ndk and Qt5.5. See step 0.
+2. cmake
+3. ant
+4. Java JDK
+5. working adb is recommended
+6. dependencies of libdivecomputer and subsurface -
+   visit http://subsurface.hohndel.org/documentation/building/
+
+Steps to install:
+
+Step 0.
+Grab..
+Android ndk from: http://developer.android.com/tools/sdk/ndk/index.html
+Android sdk from: http://developer.android.com/sdk/index.html#download
+And QT for android from: http://qt-project.org/downloads
+
+Step 1.
+Extract and install these into known directories.
+Have a look in the top of build.sh for where the cross build tool expects
+them. By default thats is: ../../../android-ndk-r9d ../../../android-sdk-linux
+and ../../../Qt/5.5
+
+Step 2.
+Run bash build.sh in the terminal. By default it builds for arm but you
+can pass x86 as first arg to build.sh to have it build for x86. Nice when
+debugging in a fast emulator.
+The script will download and build the whole dependency chain.
+
+After this, subsurface will be built for android.
+
+The output folder is subsurface-build-arm/android_build and your newly
+created apk shows up as:
+subsurface-build-arm/android_build/bin/QtApp-debug.apk
+
+Where the x86 apk shows up when built for x86 is left as a exercise for the
+reader.
