/** \class InteriorExteriorMeshFilter
* \brief
*
* InteriorExteriorMeshFilter takes an itk::Mesh and extracts from it a Sub-Mesh
* such that all its points Evaluate > 0 in an itk::SpatialFunction provided
* by the user.
*
* This filter is templated over the Input Mesh type, the Output Mesh type
* and the SpatialFunctionType. However the only requirement for the Spatial
* function is to support SmartPointers and to provide an Execute() method,
* along with a typedef for OutputType (for the type returned by Execute() ).
*
* The additional content of the mesh is passed untouched. Including the
* connectivity and the additional information contained on cells and points.
* However, attention should be paid to the cells because some of their points
* could not exist in the output mesh, if they did not satisfy the criterion
* imposed by the spatial function.
*
* \ingroup MeshFilters
