function Millis = RPI_GetMillis()
// Function to get time in millisecond since first setup function called. 
//
// Calling Sequence
//     Millis = RPI_GetMillis()
//
// Parameters
//     Millis: time in milliseconds since first setup function called    
//
// Description
//     This function can be used to get time since first setup function called. 
//	   Note: To use this function atleast one setup function must be called.
//	
// Examples
//     start = RPI_GetMillis() 
//	   RPI_DelayMilli(100) //This will delay the execution of next code by 100 ms.
//	   end = RPI_GetMillis()
//	   delay = end- start //This should be approximately 100ms.
