Parameter handling for one-dimensional polynomials.
A 1-dimensional Polynomial's parameters.
A Polynomial is described by a set of coefficients; its fundamental operation is evaluating itself at some "x". The number of coefficients is the order of the polynomial plus one.
Since the Polynomial is a Function, the derivatives can be obtained as well.
The parameter interface (see FunctionParam class), is used to provide an interface to the Fitting classes.
This class is in general used implicitly by the Polynomial class only.
