Remove ^ and @ operators for Point2D and Analytics in general

[carlos-adir]

The operators ^ and @ were removed:

• For Point2D
  • A ^ B presented as the cross product between A and B. The function cross(A, B) takes its place
  • A @ B presented as the inner product between A and B. The function inner(A, B) takes its place
• For Polynomial and Bezier
  • The @ presented the inner multiplication between two analytic functions. As the coefficients of a polynomial can also be Point2D (cause they support linear operation), then p(t) @ p(t) returned another polynomial function which coefficients were scalar.
