* @class vtkExpandSelectedGraph
* @brief expands a selection set of a vtkGraph
*
*
* The first input is a vtkSelection containing the selected vertices.
* The second input is a vtkGraph.
* This filter 'grows' the selection set in one of the following ways
* 1) SetBFSDistance controls how many 'hops' the selection is grown
* from each seed point in the selection set (defaults to 1)
* 2) IncludeShortestPaths controls whether this filter tries to
* 'connect' the vertices in the selection set by computing the
* shortest path between the vertices (if such a path exists)
* Note: IncludeShortestPaths is currently non-functional
