/**
* \mainpage BTrack - A Real-Time Beat Tracker
*
* A real-time beat tracker, implemented in C++.

* 
* Usage - C++
* -----------
* 
* **STEP 1**
* 
* Include the BTrack header file as follows:
*
* 		#include "BTrack.h"
*	
* **STEP 2**
*
* Instantiate the algorithm by one of the following:
* 
*
*		// to use the default 512 hop size and 1024 frame size
*		BTrack b; 
*
* or:	
*	
*		// to specify a hop size (e.g. 512) and have a frame size of 2 x the hop size
*		BTrack b(512); 
*	
* or:
*
*		// to specify both the hop size and frame size
*		BTrack b(512,1024);
*	
* **STEP 3.1 - Audio Input**
* 
* In the processing loop, fill a double precision array with one frame of audio samples (as determined in step 2): 
* 
*		double *frame; 
*	
*		// !
*		// do something here to fill the frame with audio samples
*		// !
*
* and then call:
*
*		b.processAudioFrame(frame);
*	
* and to check for beats, simply call:
*
*		if (b.beatDueInCurrentFrame())
*		{
*			// do something on the beat
*		}
*
* **STEP 3.2 - Onset Detection Function Input**	
*
* The algorithm can process onset detection function samples. Given a double precision onset detection function sample called 'newSamples', at each step, call:
*
*		b.processOnsetDetectionFunctionSample(newSample);
*	
* and then check for beats with:
*
*		if (b.beatDueInCurrentFrame())
*		{
*			// do something on the beat
*		}
*
