These interactions included reading audio data, seeking within an audio file, getting information about the file, and pulling the waveform data for visualizing the contents of the audio file. The EZAudioFileDelegate provides event callbacks for when reads, seeks, and various updates happen within the audio file to allow the caller to interact with the action in meaningful ways. Common use cases here could be to read the audio file's data as AudioBufferList structures for output (see EZOutput) and visualizing the audio file's data as a float array using an audio plot (see EZAudioPlot).

The x-axis goes from 0 to the number of points (pointCount) while the y-axis goes from -1 to 1. Check out the implementation of this method to see how the model view matrix of the base effect is transformed to map this properly to the viewport.
+ @param pointCount   A UInt32 representing the number of points contained in the points array.
+ @param baseEffect   An optional GLKBaseEffect to use as a default shader. Call prepareToDraw on the base effect before any glDrawArrays call.
+ @param vbo          The Vertex Buffer Object used to buffer the point data.
+ @param vab          The Vertex Array Buffer used to bind the Vertex Buffer Object. This is a Mac only thing, you can ignore this completely on iOS.
+ @param interpolated A BOOL indicating whether the data has been interpolated. This means the point data is twice as long, where every other point is 0 on the y-axis to allow drawing triangle stripes for filled in waveforms. Typically if the point data is interpolated you will be using the GL_TRIANGLE_STRIP drawing mode, while non-interpolated plots will just use a GL_LINE_STRIP drawing mode.
+ @param mirrored     A BOOL indicating whether the plot should be mirrored about the y-axis (or whatever geometry you come up with).
+ @param gain         A float representing a gain that should be used to influence the height or intensity of your geometry's shape. A gain of 0.0 means silence, a gain of 1.0 means full volume (you're welcome to boost this to whatever you want).

- The EZAudioPlayerDelegate provides event callbacks for the EZAudioPlayer. These type of events are triggered by changes in the EZAudioPlayer's state and allow someone implementing the EZAudioPlayer to more easily update their user interface. Events are triggered anytime the EZAudioPlayer resumes/pauses playback, reaches the end of the file, reads audio data and converts it to float data visualizations (using the EZAudioFile), and updates its cursor position within the audio file during playback (use this for the play position on a slider on the user interface).
- @warning These callbacks don't necessarily occur on the main thread so make sure you wrap any UI code in a GCD block like: dispatch_async(dispatch_get_main_queue(), ^{ // Update UI });

- EZAudioPlotGL is a subclass of either the EZPlot on iOS or an NSOpenGLView on OSX. I apologize ahead of time for the weirdness in the docs for this class, but I had to do a bit of hackery to get a universal namespace for something works on both iOS and OSX without any additional components. The EZAudioPlotGL provides an the same utilities and interface as the EZAudioPlot with the added benefit of being GPU-accelerated. This is the recommended plot to use on iOS devices to get super fast real-time drawings of audio streams. For the methods and properties below I've included notes on the bottom just indicating which OS they correspond to. In most (if not all) use cases you can just refer to the EZPlot documentation to see which custom properties can be setup. There update function is the same as the EZPlot as well: `updateBuffer:withBufferSize:`

-==========================================================================================
-
-0.0.1
-Initial release. 
-Components include: EZAudioFile, EZAudioPlot, EZAudioPlotGL, EZMicrophone, EZOutput, and EZRecorder. 
-Provided 6 example projects: CoreGraphicsWaveform, OpenGLWaveform, WaveformFromFile, PassThrough, Record, and PlayFile.
-
-0.0.2
-Fix for Cocoapod spec. Forgot to include files with .c extension.
-
-0.0.3 
-Changing EZAudioPlot and EZAudioPlotGL to scroll for the EZPlotTypeRolling instead of wiping the screen clean when hitting the end
-Allowed EZMicrophone EZOutput to have custom AudioStreamBasicDescription setters
-Fixed bug in EZAudioFile's getWaveformData function where it was not exiting after sending back cached waveform data (rereading from the audio file)
-Added stereo support for EZMicrophone, EZAudioFile, EZRecorder, and EZOutput
-Added more memory cleanup for EZAudioFile
-Added adjustable rolling length for EZAudioPlot and EZAudioPlotGL so those rolling graphs can now range from 128 to 8192 whereas before it was fixed at 1024
-Added adjustable resolution for waveform data coming from the EZAudioFile so output from the getWaveformDataWithCompletionBlock: function can literally be of any size. Try 128 for a low resolution waveform or 8192 for a much higher resolution waveform.
-Added quick fix for EZOutput to properly route stereo data coming from a circular buffer datasource. Next version (0.0.4) needs to add EZConverter to allow quick conversions between non-interleaved and interleaved formats.
-
-0.0.4
-Added ‘closeAudioFile’ to EZRecorder to properly dispose of internal audio file prior to trying to reload it using the EZAudioFile.
-Added new EZOutputDataSource method that provides pre-allocated AudioBufferList to fill instead of caller allocating and disposing on AudioBufferList. Much less errors.
-Added EZAudioPlayer for playback and visualization of local audio files (no network streaming yet).
-Merged bug fixes from community for EZAudio file. 
-
-0.0.5
-Added multiple destination recording formats to the EZRecorder (EZRecorderFileType)
