function out=RPI_digitalRead(pin)
// Function to read the digital voltage at the given pin
//
// Calling Sequence
//  v=RPI_digitalRead(pin)
//
// Parameters
//  pin: The pin number to read the voltage from. Numbering sequence to be followed as initiated using RPI_pinNumbering function.
//
// Description
//  This funtion reads the digital voltage at the given pin. Returns a 0 (for low) and 1 (for high). 
//  Note: pin should be set for input mode using RPI_pinMode. The function will also return 0/1 corresponding to what the voltage is set for an output pin.
//
// Examples
//  v=RPI_digitalRead(0)
