The first section of code handles the initialization. The first line, in this case, is not necessary because the
Stamp clears all variables to zero automatically. The program consists of a large loop that is executed
over, and over again. Within the main loop, the serial port is examined. If the host has sent a character,
that character is received, parsed and executed. If no characters are received within one second, or once
the received character has been parsed the monitor and control section of code is executed.
