Fredric Rice / Mbed 2 deprecated NextGen-LaserMonitor

Generates a test signal on an AnalogOut and monitors a signal on an AnalogIn, plotting the test signal or the actual signal depending on a conditional compile. The wait() and wait_ms() library calls for this board are highly inaccurate so a new function is provided to wait for X number of milliseconds -- which is not very accurate.
