 * @class   vtkXGMLReader
 * @brief   Reads XGML graph files.
 * This reader is developed for a simple graph file format based
 * loosely on the "GML" notation.  This implementation is based
 * heavily on the vtkTulipReader class that forms part of the
 * Titan toolkit.
 *
 * @par Thanks:
 * Thanks to David Duke from the University of Leeds for providing this
 * implementation.
