DI COSTANZO updated MATH-687:
-----------------------------
Attachment: jacobi.patch
Here is the patch for the Jacobi polynomials. This implementation is using a
Map of JacobiKey to store every computed polynomials for a given key value
(u,v). The cache process is used and some test have been added in to the
PolynomialsUtilsTest class.
> Add the Jacobi polynomials in the class PolynomialsUtils

> Jacobi polynomials Pk(vw) are a generalization of the legendre polynomial.
> Legendre Polynomials are Jacobi polynomials for v = w = 0.
> They are orthogonal polynomials and are defined from a recursion formula,
> giving the n+1 element of the polynomial from the nth element and the (n-1)'s
> one
> Therefore, they could be implemented in the PolynomialsUtils and use the
> generic frame already used in this class to create and store them.
