motor driver test project
begun LED control
ryan's work on front end, etc.
update LED header file

led init done
led driver added
LED driver added to scheduler

"update" flag added to global data

fixed output ports to portb

led init tested works
card reaction interrupts half working

interrupts trigger and run. Seems to output only to one led regardless
of switch pressed. Also code appears backwards. slot1 code has desired
result, but I expected slot 2-4 to work
