+In ClassCythonCPP I have implemented a simple class in C++ and wrapped it in cython such that you may create an instance in python of this class.
+
+In ClassCythoncppWithMemberFunctions I have extended this simple class to take a numpy array in the constructor and convert it to a C array stored in the object. I have then added a member function to the class which sums the elements in this list and returns a double containing this sum total. The returned number may be accessed from Python.
