* @class vtkPOpenFOAMReader
* @brief reads a decomposed dataset in OpenFOAM format
*
* vtkPOpenFOAMReader creates a multiblock dataset. It reads
* parallel-decomposed mesh information and time dependent data. The
* polyMesh folders contain mesh information. The time folders contain
* transient data for the cells. Each folder can contain any number of
* data files.
*
* @par Thanks:
* This class was developed by Takuya Oshima at Niigata University,
