Comment:
I am writing my own documentation about the transformation from cubic to
Weierstrass. I will upload it within the next few days.
I think I spotted a minor error in my patch. When P is not a flex, the
program finds a second point P2 using the chord and tangent method.
However, if P2 is a flex, I think the program will return an error. This
is a simple fix, which will be up soon.
