A one dimensional polynomial class.
A Polynomial<T> contains a set of coefficients; its fundamental operations is evaluating itself at some "x". The number of coefficients is the order of the polynomial plus one, so is the number of available parameters.
Tip: The present implementation merely stores the coefficients in a Block; In the unlikely case that we need to deal with polynomials with many zero coefficients, a more efficient representation would be possible;
