// Key things demo'd:
// 1. USB application serial, USB CDC serial, not over the debug port.
// 2. Capacitive Touch
// 3. Accelerometer
// 4. RGB LED

/** Setup the serial over USB virtual COM port.
 * Note that the connection is made over the application USB port, NOT the CMSIS-DAP USB port.
 * If you would like to use the debug/programmer USB port instead, the the following code:
 *
 * @code
 * Serial pc(USBTX,USBRX); 
 * @endcode
 *
 * Notice that the default mbed USB CDC device will block on this declaration until you attach the KL25Z board
 * to your PC's USB port and the device enumerates. After that, program execution will begin.
