-* The "Cadet-Style" keymap for the melody96.
-* Author: Yonatan Zunger (zunger@gmail.com)
-
-This is an experimental keymap being used both for practical reasons (as my daily driver) and to
-work out the ideas of a "space-cadet-style" keyboard which can type text and mathematical symbols
-with equal ease. It's designed for anyone who frequently needs to do this outside of a LaTeX
-environment, or for anyone who loves the old "Space Cadet" keyboard! And it works at its best when
-you have actual Cadet keycaps (like SA Symbolics) installed, because those keycaps will actually
-show what you get.
-
-The core idea of this keyboard is that, in addition to a QWERTY base layer and a function layer, it
-supports two additional base layers -- the GREEK layer (the analogue of the Space Cadet "Greek," or
-"Front," keys) and the CADET layer (the analogue of the Space Cadet "Top" keys). These layers use
-Unicode to generate all of the mathematical symbols you can find on a traditional Space Cadet
-layout, plus a bunch of extras.
-
-Because Unicode can't be encoded using the traditional USB HID protocol, QMK does some clever but
-horrifying things to fool your OS. One consequence of this is that the shift key needs to be handled
-by the keyboard firmware, not the host OS. To handle this, we have two additional layers --
-SHIFTGREEK and SHIFTCADET -- and handle the flipping between all of these layers here in the
-firmware.
-
-*The simple bit: Using this layout on a Melody96*
-
-At the core of this layout are three special modifier keys and two special lock keys:
-
-* The GREEK key, to the right of the spacebar, activates the GREEK layer. GREEK+SHIFT activates
-  SHIFTGREEK. These keys generate Greek letters on the letter keys (thus the name), and a few
-  mathematical symbols on other keys. They correspond to the notations on the front of traditional
-  Space Cadet keys; if your capset doesn't include those (alas, most don't), they're the "pretty
-  obvious" mappings.
-* The CADET key, to the right of GREEK, activates the CADET layer. These are the symbols above the
-  letters on a Space Cadet layout. CADET+SHIFT activates the SHIFTCADET layer, with even more
-  symbols.
-* The FUNCTION key, to the right of CADET, activates the function layer. This is where you have a
-  reset mechanism, a selector for which Unicode input type you want, and so on.
-
-Additionally, GREEK+ALT is equivalent to CADET. This is handy for other keyboards where you don't
-have room for this many modifiers.
-
-The lock keys are:
-
-* Caps lock, if you use it, will also act as a "shift lock" for the Greek and Cadet layers. Shift
-  lock is slightly different, in that while it is engaged shift will _dis_engage it; that's actually
-  pretty useful when typing math.
-* An additional "layer lock" key, by default where "num lock" usually goes, will lock the choice of
-  base layer. To use it, hold down any invocation of the GREEK or CADET layers, or none at all, and
-  hit lock; it will then put you in that layer. The corresponding modifier key will then toggle you
-  back to the QWERTY layer. (So for example, if you hit GREEK+LAYER_LOCK and release them, you're
-  now typing in Greek; the GREEK modifier would cause you to type QWERTY momentarily. To go back to
-  ordinary QWERTY mode, you'd just hit LAYER_LOCK again with no modifiers held)
-
-To see the full layout, check out the big comment in keymap.c.
-
-*A less-simple bit: Adapting this to other keyboards*
-
-This is really a canary for generic Cadet implementations. Before this can be made generic, a few
-things will have to happen:
-
-(1) Instead of a fixed keymap, this has to be refactored into some kind of array showing the
-mappings of QWERTY-layer keys onto the appropriate code points in the GREEK and CADET layers, and
-some preprocessor magic needs to auto-transform this plus a traditional keymap for the QWERTY layer
-into keymaps for all five of the core layers. (Function layers would presumably be handled on a
-per-keyboard basis)
-
-(2) The standard mapping of those should have some #define's to control things like whether there
-are physical F-keys (you would probably want to move superscript and subscripts onto the numbers if
-there weren't, and figure out what to do with the non-numeric super/sub keys), whether you actually
-want to enable GREEK+ALT=CADET, and so on;
-
-(3) There should be support for controlling indicator LEDs based on the base layer selection,
-caps/shift lock state, and layer lock state, as well as for triggering audio on transitions;
-
-(4) All the core fancy logic in process_record_user which implements the layer handling should be
-factored out into its own function, so that keyboards can easily reuse that, too.
-
-This is a lovely TODO for future work, and could be particularly fun to go along with new releases
-of SA Symbolics and the like. Anyone interested in such things, ping me!
