/**
 * @class   vtkFacetReader
 * @brief   reads a dataset in Facet format
 *
 * vtkFacetReader creates a poly data dataset. It reads ASCII files
 * stored in Facet format
 *
 * The facet format looks like this:
 * FACET FILE ...
 * nparts
 * Part 1 name
 * 0
 * npoints 0 0
 * p1x p1y p1z
 * p2x p2y p2z
 * ...
 * 1
 * Part 1 name
 * ncells npointspercell
 * p1c1 p2c1 p3c1 ... pnc1 materialnum partnum
 * p1c2 p2c2 p3c2 ... pnc2 materialnum partnum
 * ...
