Arduino-Rainbowduino I2C Slave - PulseIn input replicator

/*I haven't gotten around to properly commenting this yet.  If I don't soon, yell at me.  This code takes pulseIn input values as single-byte characters from I2C and translates them into usable integers.  This is writen specifically for the Rainbowduino, who doesn't have any inputs.*/
