+// Function to initialize lcd
+//
+// Calling Sequence
+//  RPI_lcdInit(rows,cols,bits,rs,strb,d0,d1,d2,d3,d4,d5,d6,d7)
+//
+// Parameters
+//  rows: numer of rows in lcd
+//  cols: numer of colums in lcd
+//  bits: number of bits wide on the interface (4 or 8) 
+//  rs  : pin number of display RS
+//  strb: pin number of strobe (E)
+//  d0  : pin number of data pin 1
+//  d1  : pin number of data pin 2
+//  d2  : pin number of data pin 3
+//  d3  : pin number of data pin 4
+//  d4  : pin number of data pin 5
+//  d5  : pin number of data pin 6
+//  d6  : pin number of data pin 7
+//  d7  : pin number of data pin 8
+//
+// Description
+//  This function initalizes an lcd display attaced to the Raspberry pi. The return value is the file-descriptor to be used for all subsequent calls to the lcd library when dealing with that LCD, or -1 to indicate a fault. (Usually incorrect parameters)
+//
+//  The numberin sequence to be followed as initiated using RPI_pinNumbering
+//
+// Examples
+//  fd=RPI_lcdInit (2,16,8,11,10,0,1,2,3,4,5,6,7) ;
+// See also
