/**
* @class vtkGAMBITReader
* @brief reads a dataset in Fluent GAMBIT neutral file format
*
* vtkGAMBITReader creates an unstructured grid dataset. It reads ASCII files
* stored in GAMBIT neutral format, with optional data stored at the nodes or
* at the cells of the model. A cell-based fielddata stores the material id.
*
* @par Thanks:
* Thanks to Jean M. Favre (CSCS, Swiss Center for Scientific Computing) who
