/**
* @class vtkReverseSense
* @brief reverse the ordering of polygonal cells and/or vertex normals
*
*
* vtkReverseSense is a filter that reverses the order of polygonal cells
* and/or reverses the direction of point and cell normals. Two flags are
* used to control these operations. Cell reversal means reversing the order
* of indices in the cell connectivity list. Normal reversal means
* multiplying the normal vector by -1 (both point and cell normals,
* if present).
*
* @warning
* Normals can be operated on only if they are present in the data.
