gitignore: add ignores for Debug folder and other build artifacts (.d, .o)
UART: Change comments
PID: Add tick timer

The tick timer runs at 1ms.
Init: Add motor module to module init function
UART: Change to 19200 baud
PID: Add motor channel freq. measurement timer

Rising/Falling edges on PORTE pin 0 will trigger a frequency measurement operation in TCE0.
Resulting CCA values are stored in an array that is used to generate an averaging filter.
Average is returned from the measureCCA function, and is updated every time CCA is changed.
PID: Add ability to measure rad/s on all wheels in parallel

Added structs to contain pid data for wheels.
Added initializations for wheel freq. measurement timer channels.
Implemented constant multiplier to convert cca into rad/s.
Implemented function to measure rad/s on wheel
PID: Add basic PID algorithm, initializations, and control functions
PID: Tune PID gains, Add Processing script to visualize tuning process
PID: Move ports and timers to configuration values
Update README.md to include information about floating point numbers in printf routines
