Added extra functionality to Point class( an iterator ) and PersistenceDiagram( dimension property and __len__ func ). persistence-diagram.h: Added a new read-only dimension member and member function to access it. With a new constructor that that takes in an int type to initialize dimension. persistence-diagram.cpp: Added new bp::init constructor. Takes in an integer type to initialize the dimension. Exposed the dimension property. Exposed the size property via a __len__ method. __init__.py: Added an iterator for Point objects. This iterates over the coords and then the data( if present ).
