int(* ltc_math_descriptor::ecc_map)(ecc_point *P, void *modulus, void *mp)

ECC mapping from projective to affine, currently uses (x,y,z) => (x/z^2, y/z^3, 1)

P The point to map
modulus The modulus
mp The "b" value from montgomery_setup()
CRYPT_OK on success
The mapping can be different but keep in mind a ecc_point only has three integers (x,y,z) so if you use a different mapping you have to make it fit.
