+/** The Model 01's key layouts are defined as 'keymaps'. By default, there are three
+  * keymaps: The standard QWERTY keymap, the "Function layer" keymap and the "Numpad"
+  * keymap.
+  *
+  * Each keymap is defined as a list using the 'KEYMAP_STACKED' macro, built
+  * of first the left hand's layout, followed by the right hand's layout.
+  *
+  * Keymaps typically consist mostly of `Key_` definitions. There are many, many keys
+  * defined as part of the USB HID Keyboard specification. You can find the names
+  * (if not yet the explanations) for all the standard `Key_` defintions offered by
+  * Kaleidoscope in these files:
+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/key_defs_keyboard.h
+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/key_defs_consumerctl.h
+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/key_defs_sysctl.h
+  *    https://github.com/keyboardio/Kaleidoscope/blob/master/src/key_defs_keymaps.h
+  *
+  * Additional things that should be documented here include
+  *   using ___ to let keypresses fall through to the previously active layer
+  *   using XXX to mark a keyswitch as 'blocked' on this layer
+  *   using ShiftToLayer() and LockLayer() keys to change the active keymap.
+  *   the special nature of the PROG key
+  *   keeping NUM and FN consistent and accessible on all layers
+  *
+  *
+  * The "keymaps" data structure is a list of the keymaps compiled into the firmware.
+  * The order of keymaps in the list is important, as the ShiftToLayer(#) and LockLayer(#)
+  * macros switch to key layers based on this list.
+  *
+  *
+
+  * A key defined as 'ShiftToLayer(FUNCTION)' will switch to FUNCTION while held.
+  * Similarly, a key defined as 'LockLayer(NUMPAD)' will switch to NUMPAD when tapped.

+  * the numbers 0, 1 and 2.
