CurveEval: Add total_length() and total_control_point_size() methods

Add the following methods to the CurveEval class:
total_length() : returns the total length of the curve without needing to
                    allocate a new array
total_control_point_size() : returns the total number of control points without
                    needing to allocate a new array
