/** \class VideoFileReader
* \brief Reader that creates a VideoStream
*
* This class is responsible for reading video information from files. It is a
* subclass of VideoSource, giving it functionality to connect to other
* TemporalProcessObject classes (specifically, VideoToVideoFilter classes). It
* uses the temporal streaming implementation provided by TemporalProcessObject
* to load a single frame at a time into the frame buffer of the output
* VideoSource.
