 *         The public class Polynomial describes the structure of a polynomial,
 *         i.e. it has a degree and an array of coefficients. It also contains
 *         the method normalizePoly, which says that if a n-degree polynomial
 *         has the n-coefficient zero, then it is actually of n-1 degree.
