/**
* @class vtkBlankStructuredGrid
* @brief translate point attribute data into a blanking field
*
*
* vtkBlankStructuredGrid is a filter that sets the blanking field in a
* vtkStructuredGrid dataset. The blanking field is set by examining a
* specified point attribute data array (e.g., scalars) and converting
* values in the data array to either a "1" (visible) or "0" (blanked) value
* in the blanking array. The values to be blanked are specified by giving
* a min/max range. All data values in the data array indicated and laying
* within the range specified (inclusive on both ends) are translated to
* a "off" blanking value.
