function out=RPI_mcp23016Setup(pinBase,i2cAddress)
// Function for setting up 16-bit MCP23016 I2C GPIO expansion chip.
//
// Calling Sequence
//  RPI_mcp23016Setup(pinBase,i2cAddress)
//
// Parameters
//  pinBase  : any number above 64. The consecutive 16 pins will be allocated alongwith.
//  i2cAdress: integer, the I2C address obtained using RPI_i2cdetect function
//
// Description
//  This function sets up the extension module for the MCP23017 (16-bit) I2C GPIO expansion chips. The MCP23016 is the fore-runner of the MCP23017 GPIO expansion chip and may be present on some older interface boards.
