function RPI_gertboardAnalogWrite(pin,value)
// Function to write voltage value to pins on gertboard
//
// Calling Sequence
//  RPI_gertboardAnalogWrite(pin,value)
//
// Parameters
//  pin  : the pin to read the voltage from. Numbering follows the pinBase from RPI_gertboardSetup function.
//  value: voltage value to write
//
// Description
//  After initialinzing the pinBase using the RPI_gertboeardSetup function, writing pinBase + 0 outputs to the first analog output channel. (Pin AD0).
//
// Examples
//  RPI_gertboardAnalogWrite(100,100)
