 Function
     Roach_Init

 Parameters
    None.

 Returns
     SUCCESS if operation successful
     ERROR  otherwise

 Description
      Performs all the initialization necessary for the roach.
      this includes initializing the PWM module, the A/D converter, the
      data directions on some pins, and setting the initial motor directions.
 Notes
     None.
