return a subgraph of a vtkGraph
The first input is a vtkGraph to take a subgraph from. The second input (optional) is a vtkSelection containing selected indices. The third input (optional) is a vtkAnnotationsLayers whose annotations contain selected specifying selected indices. The vtkSelection may have FIELD_TYPE set to POINTS (a vertex selection) or CELLS (an edge selection). A vertex selection preserves all edges that connect selected vertices. An edge selection preserves all vertices that are adjacent to at least one selected edge. Alternately, you may indicate that an edge selection should maintain the full set of vertices, by turning RemoveIsolatedVertices off.
