/**
* @file QuadraticNumericalMathEvaluationImplementation.hxx
* @brief Class for a quadratic numerical math function implementation
* of the form y = constant + <linear, x-c> + <<quadratic, x-c>, x-c>
* where constant is a dim(y) numerical point, c a dim(x) numerical
* point, linear is a dim(x) by dim(y) matrix, quadratic is a
* dim(x) by dim(x) by dim(y) symmetric tensor and <linear, x>
* means Transpose(linear).x, <quadratic, x> means
* Transpose_kj(quadratic).x
