ErgoDox EZ Code Friendly Qwerty Layout

This layout aims to balance muscle memory from a typical QWERTY layout with having keys used for software development easily accessible.

The this layout is a normalized qwerty, with some configurable keys left thumb cluster so you can use it more as needed.
Arrow keys follow VIM convention (the media layer even uses arrow keys for HJKL).
On the top row only symbols are used (not numbers), it's expected the symbol layer's number-pad layout will be used for numbers.
Symbols match regular QWERTY. except for '()' which are grouped with other brackets. In their place -/= keys are placed, which almost matches a regular layout.
Brackets are placed symmetrically along the center edges, if using keys from both sides is inconvenient - the symbol layer has macros at the same key locations to type matching pairs.
The space-bar on the lower-left looks like it's in an obscure location, however using the larger thumb cluster ended up being more of a reach while typing.

Configuration

Some optional behavior is configurable without editing the code using CFQ_ prefixed defines which can be set by passing EXTRAFLAGS to make.

CFQ_USER_KEY0 (0..7) are used for custom-keys
CFQ_USE_MOMENTARY_LAYER_KEYS is used to prevent layer keys from toggling when tapped.
CFQ_USE_SHIFT_QUOTES an optional handy shortcut for writing quotes that inserts the cursor between the quotation marks.

Holding LShift, then RShift types: "" (then presses left).

Holding RShift, then LShift types: '' (then presses left).
CFQ_WORD_[A-Z] defines can bind a key to an entire user defined word.
CFQ_USE_80_KEYS enables 80 key layout, none of the extra keys are bound, they need to be set with defines: CFQ_USER_K80_L0K0 .. CFQ_USER_K80_L3K4. Where L# is the layer and K# is the key.

Notes:

The double bracket keys on this layer press left to position the cursor between them.
The left thumb cluster is used for macro record/replay.
