Pressure sensor demonstration application entry.

After initializing the development platform and sensors, this application attaches a descriptor to the sensor on an Xplained pressure sensor board. The sensor pressure and temperature data, which is formatted and printed via printf() after being read, can be viewed with a terminal application on a machine attached to the serial interface on the development board.
