+cbbrowne custom keyboard
+==============================
+
+Due to cbbrowne@acm.org
+Christopher Browne
+
+This was originally based on the default keyboard map, but I have been
+doing sundry experimentation:
+
+1. Experiments
+----------------------------------------
+
+ * To figure things out about the toolset
+ * I'm an Emacs guy, so will be needing a fair bit of tuning
+ * It made sense to mess around some with keyboard maps.
+   - I tried added Workman alongside Dvorak and Colemak
+     - Boy, oh boy, these don't help!!!
+     - I have done 30 years of learning of Emacs key mappings, and
+       these alternative keyboards massively mess me up
+   - I added a keypad, originally based on keymaps/numpad.c, but
+     mighty substantially revised, as that one seems to be rotated 90
+     degrees from usual conventions for number pads
+ * The keypad layer also includes some sample "hacks" of cool things,
+   all using actions attached in using the function action_get_macro()
+   - Key [1][2] aka "q" types out my name, cbbrowne, as a fun example
+     of a key generating a bunch of keystrokes.  The keystroke is
+     sufficiently inconvenient that it isn't terribly practical for me
+     to use it, but hey, it shows how others might use this facility
+     in a more useful context.
+   - Key [2][2] aka "a" uses a random number generator to select a digit 0-9 at random
+   - Key [3][2] aka "z" uses a random number generator to select a letter a-z at random
+   - Key [1][3] aka "e" spits out the keymap version number
+
+2. Some code structure ideas
+---------------------------------------------------
+
+   Each layer is given a name to aid in readability, which is then
+   used in the keymap matrix below.  The underscores do not denote
+   anything - you can have a layer called STUFF or any other name.
+
+   Layer names don't all need to be of the same length, obviously, and
+   you could also skip them entirely and just use numbers, though that
+   means needing to manage the numbers.
+
+   It is preferable to keep the symbols short so that a line worth of
+   key mappings fits compactly onto a line of code.  It might be an
+   interesting idea to express the maps rotated 90%, so that you
+   only need to fit 4 symbols onto each line, rather than 12.
+
+   I used enums to manage layer IDs and macro IDs so that I don't need
+   to care (beyond "start at 0", and arguably that's not needed) about
+   their values.
+
+3. Things I did not like about the default mapping
+---------------------------------------------------------
+
+   * I found control too hard to get to.  I use it more than Tab, so
+     switched it there.
+   * Having dash on [lower-j] is a bit nonintuitive, but may be OK
+   * I switched ESC/TAB/M(0) around
+   * I'm suspicious that I want to shift M(0) from [4][1] to [4][2],
+     and shift ESC off the first column so KC_LCTL and KC_LALT can
+     be on the first column.
+   * I needed to swap ' and ENTER
