Class lsst::afw::math::BasePolynomialFunction2

template<typename ReturnT>
class BasePolynomialFunction2 : public lsst::afw::math::Function2<ReturnT>

Base class for 2-dimensional polynomials of the form:

f(x,y) =   c0 f0(x) f0(y)                                        (0th order)
         + c1 f1(x) f0(x) + c2 f0(x) f1(y)                       (1st order)
         + c3 f2(x) f0(y) + c4 f1(x) f1(y) + c5 f0(x) f2(y)      (2nd order)
         + ...

and typically f0(x) = 1
