 *  \struct nitf_ImageSource
 *  \brief The base for harnessing a source.
 *
 *  The image source holds a BandSource for every band.
 *  In the single band solution, this is particularly straightforward
 *  and performance oriented.  However, it also satisfies our requirement
 *  to keep the bands separate, without require them to live in core.
 *
 *  This object will be added to the ImageSegment using the
 *  addImageSource() method
