// ModuleClockedRandom is a clocked random number generator.  The output ranges
// from 0 to 4095.
//
// Example usage:
//
//    ModuleWavetableOsc *osc = new ModuleWavetableOsc();
//    ModuleClockedRandom *clocked_random = new ModuleClockedRandom();
//    ModuleExtClock *ext_clock = new ModuleExtClock(120, EIGHTH_NOTE_CLOCK_DIVISION);
//
//    ext_clock->clock_input = inputs->gate;
//
//    clocked_random->clock_input = ext_clock;
//
//    osc->frequency_input = clocked_random;
//
//    this->last_module = osc;
