* @class vtkPHyperTreeGridProbeFilter
* @brief probe a vtkHyperTreeGrid in parallel
*
* Heavily modeled after the vtkPProbeFilter and vtkProbeFilter, this class
* is meant to be used to probe vtkHyperTreeGrid objects in parallel.
*
* This filter works correctly only if the whole geometry dataset
* (that specify the point locations used to probe input) is present on all
* nodes.
*
* @note The implicit array strategy is not available in distributed yet.
*
* @sa vtkHyperTreeGridProbeFilter
*
* Possible optimizations:
* - Enrich the parallelism logic allowing distributed input/outputs support
* with distributed HTG sources
* - Support implicit arrays (once vtkHyperTreeGrids are able to generate global IDs)
