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.
