Comment(by evanandel):
Did all of the tests work for you? The riemann tests go fine, but the
interpolators do this:
{{{

line 52:
sage: m = Riemann_Map([lambda x: ps.value(real(x))], [lambda x:
ps.derivative(real(x))],0)
Exception raised:

I can solve this by wrapping the fast-callable casts in a try except
block, but of course that means that it isn't using them for unusual
functions like the interpolators.
