* @class vtkCleanArrays

* vtkCleanArrays is a filter used to remove (or fill up) partial arrays in a
* vtkDataSet (or a vtkCompositeDataSet) across processes (and blocks).
* Empty dataset on any processes is skipped and doesn't affect the array pruned
* (or filled) in the output. This filter also handles certain non-composite
* data objects such a tables.
