First attempt at creating an interrupt to toggle an LED, but doesn't currently work
Added printing to LCD, changed to set register values (fixed a couple bugs to get it working), added storing and restoring the SREG (status register).
First attempt at writing timer drivers for timer0, doesn't get called yet.
Added breaks for all the switch statements, added setting timer 0 WGM, all unused timers will return 0 for getting the counter
Disable interrupts at the beginning of the program, use functions to control timers (not setting registers directly).
Turn red LED on right away before enabling interrupts
Added busy wait loop for 10ms so that green LED toggles based on that loop-wait, also changed period to 1000ms (500ms toggle) instead of 2000ms (1000ms toggle).
Refactor toggling red and green LEDs to their own functions
Added functionality for timer 3 drivers to work
Added toggling yellow LED based on timer 3, refactor timer periods to #defines
Corrected spelling for 'prescaler'
Refactored default LED value
