Added code to expose the persistence_diagram class, the bottleneck_distance function and the point class to python. Most of the commonly used methods for each class have been exported. The constructor for point now requires that a data argument be provided along with x and y coord. This needs to be made optional. The constructor for persistence_diagram could possibly be rewritten as well.

Consider using two simulators instead of one to make sure that trajectory
changes are processed before simplex swaps.
