// .NAME vtkDijkstraGraphGeodesicPath - Dijkstra algorithm to compute the graph geodesic.
// .SECTION Description
// Takes as input a polygonal mesh and performs a single source shortest
// path calculation. Dijkstra's algorithm is used. The implementation is
// similar to the one described in Introduction to Algorithms (Second Edition)
// by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and
// Cliff Stein, published by MIT Press and McGraw-Hill. Some minor
// enhancement are added though. All vertices are not pushed on the heap
// at start, instead a front set is maintained. The heap is implemented as
// a binary heap. The output of the filter is a set of lines describing
// the shortest path from StartVertex to EndVertex.
//
// .SECTION Caveats
// The input polydata must have only triangle cells.
//
// .SECTION Thanks
// The class was contributed by Rasmus Paulsen.
// www.imm.dtu.dk/~rrp/VTK . Also thanks to Alexandre Gouaillard and Shoaib
// Ghias for bug fixes and enhancements.
