Synopsis

A Power Logarithmic Polynomial<T> contains a set of coefficients; its fundamental operations is evaluating itself at some "x".

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;
