MMP method with A-star heuristic

Computes shortest path between given source and target using MMP method with A-star heuristic. Computes exact shortest paths. The output is a text file containing a sequence of points. To optimize time requirements this code does not maintain the inner frontier queue described in Section 3.4 of http://www.cs.unc.edu/~verma/shortest_path.pdf .

Example Usage:

---

General

Usage:

mmp -i input_mesh -o output_path_file -s source_index_number -t target_x_coordinate target_y_coordinate target_z_coordinate
-TOL tolerance_for_target_coordinates

Note: If the input mesh has been ordered using Dijkstra-based reordering, then the index of source is 1.
