   *  \section Module Description
   *  Hardware buttons driver. This provides an easy to use driver for the hardware buttons present on many boards.
   *  It provides a way to easily configure and check the status of all the buttons on the board so that appropriate
   *  actions can be taken.
   *
   *  If the BOARD value is set to BOARD_USER, this will include the /Board/Dataflash.h file in the user project
   *  directory. Otherwise, it will include the appropriate built in board driver header file.
