Dual UART Datastream

/*******************************************************************************

 Bare Conductive MPR121 library
 ------------------------------
 
 DataStream.ino - prints capacitive sense data from MPR121 to serial port
 
 Based on code by Jim Lindblom and plenty of inspiration from the Freescale 
 Semiconductor datasheets and application notes.
 
 Bare Conductive code written by Stefan Dzisiewski-Smith and Peter Krige.
