// NAME
//
//   iodebug - a module to hide the absence of hardware interface.
//
// SYNOPSYS
//
//   This module implements a subset of the bonescript interface for the
//   purpose of debug. It is used if the bonescript module is not accessible.
//
//
// DESCRIPTION
//
//   var io = require('./iodebug');
//
//   io.pinMode (pin, mode);
//
//   io.digitalWrite (pin, value);
//
//   io.digitalRead (pin);
//
//   io.attachInterrupt (pin, flag, edge, callback);
//
