- Added AddModule CMake function which simplifies specifying module requirements

- Code should be working, but much is untested
- All of the old modules will need to update and use the new DefaultMap keymap
- There might still be some naming conflicts with some Scan Modules

- Includes serial putchar and getchar cleanup (overall)
- Moved avr-capsense to DPH (renaming)
- Basic cleanup for including CLI on the avr architecture

- Adding "template" keymap
- Removed "stray" functions, variables
- Cleaned up warnings
- Now builds
- Added buffered macro integration (rather than dealing with USB directly)
- Updated the print messages to use the Kiibohd print header

TODO
- Add generic matrix integration (this will require some changes to the matrix code)
- Add more comments...lots more
- Clean up dead code

- All modules have a default avr compatibilty right now (since that is what they were developed on)
- As modules get tested and added, arm support has to be turned on in the respective setup.cmake file

- Parent module no longer allows for a stand-alone compile
- Added HeathZenith matrix (pinout still needs to be done)
- Updated the HeathZenith keymaps
- Changed the original example matrix.h to matrix_template.h

- Layouts should be changed as per defines in the Scan modules
- Which are then mapped using the macro module (if possible)

- Includes new "table pinning" setup (much easier to understand)
- Matrix layouts will be split into their own dependent modules later
- Changed the HID Raw view id (too many teensy devices on this
  computer...)
- Moved the macro processing outside of the usb timer signal
  (this will be slower overall, but will result in more consistant
  behaviour)

- main.c is now mostly complete
- Required fixes to matrix.c (some are temporary)

- Providing HEAD_DIR variable that can be prepended to refer to the top of the source directory

- Include option is currently "hacked" and needs to be fixed
- Builds on Linux, but Mac and Windows needs to be tested
- Loader script generation isn't complete
