function out=RPI_analogRead(pin)
// Function to read the analog voltage at the given pin
//
// Calling Sequence
// v=RPI_analogRead(pin)
//
// Parameters
// pin: The pin number to read the voltage from. Numbering sequence to be followed as initiated using RPI_pinNumbering function.
//
// Description
// This function returns the value read on the supplied analog input pin. Additional analog modules need to be registered to enable this function for devices such as the Gertboard, quick2Wire analog board, etc.
//
// Examples
// v=RPI_analogRead(0)
