ArgumentError: argument 4: <type 'exceptions.TypeError'>: expected
vec2d instance instead of vec2d

As far as I can tell, It's getting a vec2d, and it wants a vec2d. I't
seems like it doesn't know what it wants, but I thought only teenagers
did that, no programming languages. clearly, Im missing something.

Line 147 reads:
        moi = cp.cpMomentForCircle(self.mass, .2, 0, vec2d((0,0)))
