Subject: Large refactoring around changes in the graph class.   - Graphs now
 use lists of references instead of vectors of indicies.   - Vertices and
 edges have associated classes that can be given arbitrary properties via
 template specification.   - All essential library headers have been combined
 into one, wolff.hpp.
