EZAudioDisplayLink

@interface EZAudioDisplayLink : NSObject

The EZAudioDisplayLink provides a cross-platform (iOS and Mac) abstraction over the CADisplayLink for iOS and CVDisplayLink for Mac. The purpose of this class is to provide an accurate timer for views that need to redraw themselves at 60 fps. This class is used by the EZAudioPlot and, eventually, the EZAudioPlotGL to provide a timer mechanism to draw real-time plots.
