/* max 24 relay controller and pump pulser simulator
this program takes a serial string like this "12.900.14.14" and parses it up into variables
for relay count 1-12, number of pulses, pulse width, and delay beween pulses.
Then it prints that to the serial port like this "Relays 12 Pulses 900 Length 14ms Delay 14ms"
