/**
 * This class is the base class for orthogonal polynomials.

 * 
Orthogonal polynomials can be defined by recurrence relations like:
 * 
 *      O0(X)   = some 0 degree polynomial
 *      O1(X)   = some first degree polynomial
 *  a1,k Ok+1(X) = (a2,k + a3,k X) Ok(X) - a4,k Ok-1(X)
 * 
 * where a1,k, a2,k, a3,k and
 * a4,k are simple expressions which either are
 * constants or depend on k.
