// .NAME vtkBoostPrimMinimumSpanningTree - Contructs a minimum spanning
// tree from a graph, start node, and the weighting array
//
// .SECTION Description
//
// This vtk class uses the Boost Prim Minimum Spanning Tree
// generic algorithm to perform a minimum spanning tree creation given
// a weighting value for each of the edges in the input graph and a
// a starting node for the tree.
// A couple of caveats to be noted with the Prim implementation versus the
// Kruskal implementation:
// 1. The negate edge weights function cannot be utilized to obtain a
// 'maximal' spanning tree (an exception is thrown when negated edge weights
// exist), and
// 2. the Boost implementation of the Prim algorithm returns a vertex
// predecessor map which results in some ambiguity about which edge from
// the original graph should be utilized if parallel edges between nodes
// exist; therefore, the current VTK implementation does not copy the edge
// data from the graph to the new tree.
