Jacob Alexander 0102d05c86 Fixing clang compilation and supporting clang-tidy
- clang.c includes necessary functions to make clang compiler work (tested on teensy 3.1)
- Added support code to generate a compile_commands.json for clang-tidy
  * Updates the symlink whenever cmake or make is called (Unix OSs only)
