/*
 * The following class is created to assist in processor pin configuration and
 * operation for GPIO and special functions. Each pin is defined by the system
 * in the `\nburn<Platform>\system` and `\nburn<Platform>\include` directories for
 * the specific platform you are using.
 *
 * Examples:
 *  Pins[32] = 1;                     Set pin 32 high
 *  Pins[32] = 0;                     Set pin 32 low
 *  Pins[32].hiz();                   Set pin 32 to be a high impedance input
 *  BOOL bpinstate = Pins[32];        Set the pin to be an input and read
 *  if( !Pins[32] )
 *     iprintf( "The pin is low" );
