// .NAME vtkCollapseGraph - "Collapses" vertices onto their neighbors.
// .SECTION Description
//
// 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
