/**
* @class vtkCONVERGECFDReader
* @brief Reader for CONVERGE CFD post files.
*
* This class reads CONVERGE CFD post files containing meshes, surfaces,
* and parcels. Each stream in a file is read as a top-level
* block and meshes, surfaces, and parcels are datasets under
* each stream block.
*
* Cell data arrays associated with mesh cells can be individually
* selected for reading using the CellArrayStatus API.
*
* Point data arrays associated with parcels can be individually selected
* for reading using the ParcelArrayStatus API.
*
* Time series are supported. The reader assumes a time series is defined
* in a sequence of files that follow the naming convention
*
* \code
* <prefix><zero-padded index>[_][<time>].h5
* \endcode
*
* where the prefix is determined from the FileName property passed to
* the reader. The underscore and time elements are optional. The time
* value associated with each file is read from metadata in the file.
*
* Parallel data loading is not supported.
