/**
 * @class   vtkResampleWithDataSet
 * @brief   sample point and cell data of a dataset on
 * points from another dataset.
 *
 * Similar to vtkCompositeDataProbeFilter, vtkResampleWithDataSet takes two
 * inputs - Input and Source, and samples the point and cell values of Source
 * on to the point locations of Input. The output has the same structure as
 * Input but its point data have the resampled values from Source. Unlike
 * vtkCompositeDataProbeFilter, this filter support composite datasets for both
 * Input and Source.
