// .NAME vtkMFIXReader - reads a dataset in MFIX file format
// .SECTION Description
// vtkMFIXReader creates an unstructured grid dataset. It reads a restart
// file and a set of sp files.  The restart file contains the mesh 
// information.  MFIX meshes are either cylindrical or rectilinear, but 
// this reader will convert them to an unstructured grid.  The sp files 
// contain transient data for the cells.  Each sp file has one or more 
// variables stored inside it.  

// .SECTION Thanks
// Thanks to Phil Nicoletti and Brian Dotson at the National Energy 
// Technology Laboratory who developed this class.
