/**
* @class vtkQuantizePolyDataPoints
* @brief quantizes x,y,z coordinates of points
*
* vtkQuantizePolyDataPoints is a subclass of vtkCleanPolyData and
* inherits the functionality of vtkCleanPolyData with the addition that
* it quantizes the point coordinates before inserting into the point list.
* The user should set QFactor to a positive value (0.25 by default) and all
* {x,y,z} coordinates will be quantized to that grain size.
*
* A tolerance of zero is expected, though positive values may be used, the
* quantization will take place before the tolerance is applied.
*
* @warning
* Merging points can alter topology, including introducing non-manifold
* forms. Handling of degenerate cells is controlled by switches in
* vtkCleanPolyData.
*
* @warning
* If you wish to operate on a set of coordinates that has no cells, you must
* add a vtkPolyVertex cell with all of the points to the PolyData
* (or use a vtkVertexGlyphFilter) before using the vtkCleanPolyData filter.
