/**
* @class vtkEnSight6Reader
* @brief class to read EnSight6 files
*
* vtkEnSight6Reader is a class to read EnSight6 files into vtk.
* Because the different parts of the EnSight data can be of various data
* types, this reader produces multiple outputs, one per part in the input
* file.
* All variable information is being stored in field data. The descriptions
* listed in the case file are used as the array names in the field data.
* For complex vector variables, the description is appended with _r (for the
* array of real values) and _i (for the array if imaginary values). Complex
* scalar variables are stored as a single array with 2 components, real and
* imaginary, listed in that order.
* @warning
* You must manually call Update on this reader and then connect the rest
* of the pipeline because (due to the nature of the file format) it is
* not possible to know ahead of time how many outputs you will have or
* what types they will be.
* This reader can only handle static EnSight datasets (both static geometry
* and variables).
