// 
// ModuleCounter is used for counting up from 0 to a target number (inclusive).  
// Once the target number has been reached, the output loops back to 0. 
// The target number is passed into ModuleCounter's constructor.   The counter
// is incremented in response to a positive clock pulse at the clock input.
//
// Here's an example which uses a counter to cycle through the first 6 
// equations of the wavetable module:
//
//   ModuleCounter *counter = new ModuleCounter(5);  // count from 0 to 5
//   ModuleClock *bpm_clock = new ModuleClock(120, EIGHTH_NOTE_CLOCK_DIVISION);  // clock at 120BPM
//   ModuleWavetableOsc *wavetable_osc = new ModuleWavetableOsc();
//
//   counter->clock_input = bpm_clock;
//   wavetable_osc->wavetable_input = counter;
//   wavetable_osc->frequency_input  = inputs->sr;
//
//   this->last_module = wavetable_osc;
