/**
* @brief Nth degree Polynomial with one variable
*
* This is a derived class from Basis1VariableFunction which provides the
* capabilities of a polynomial equation in one variable with degree n, where n
* is specified during the object construction. For example, Degree = 1 z = a +
* b*x Degree = 2 z = a + b*x + c*x**2 Degree = 3 z = a + b*x + c*x**2 + d*x**3
* In general the number of coefficients will be degree + 1.
