/**
* @class vtkCollapseGraph
* @brief "Collapses" vertices onto their neighbors.
*
*
* vtkCollapseGraph "collapses" vertices onto their neighbors, while maintaining
* connectivity. Two inputs are required - a graph (directed or undirected),
* and a vertex selection that can be converted to indices.
*
* Conceptually, each of the vertices specified in the input selection
* expands, "swallowing" adacent vertices. Edges to-or-from the "swallowed"
* vertices become edges to-or-from the expanding vertices, maintaining the
* overall graph connectivity.
*
* In the case of directed graphs, expanding vertices only swallow vertices that
* are connected via out edges. This rule provides intuitive behavior when
* working with trees, so that "child" vertices collapse into their parents
* when the parents are part of the input selection.
*
* Input port 0: graph
* Input port 1: selection
