// .NAME vtkPMultiResolutionGenericIOReader
// .SECTION Description
// This reader handles multiple GenericIO files that are different resolutions
// of the same dataset. This reader aggregates these and allows streaming
// different resolutions on different parts of the dataset. It has the
// concept of a resolution level with 0 being the lowest resolution and the
// resolution increases as the level number increases.
