/** \class VideoIOBase
* \brief Abstract superclass defines video IO interface.
*
* VideoIOBase is a class that reads and/or writes video data
* using a particular external technique or external library (OpenCV, vxl). The
* VideoIOBase encapsulates both the reading and writing of data. The
* VideoIOBase is used by the VideoFileReader class (to read data)
* and the VideoFileWriter (to write data). Normally the user does not directly
* manipulate this class directly.
*
* A Pluggable factory pattern is used. This allows different kinds of
* readers to be registered (even at run time) without having to
* modify the code in this class.
