   *  \brief LUFA Custom Board Button Hardware Driver (Template)
   *
   *  This is a stub driver header file, for implementing custom board
   *  layout hardware with compatible LUFA board specific drivers. If
   *  the library is configured to use the BOARD_USER board mode, this
   *  driver file should be completed and copied into the "/Board/" folder
   *  inside the application's folder.
   *
   *  This stub is for the board-specific component of the LUFA Buttons driver,
   *  for the control of physical board-mounted GPIO pushbuttons.
