CURVE:BIQUADRATIC

Quadratic curve with two independent variables. Input consists of the curve name, the six coefficients, and min and max values for each of the independent variables. Optional inputs for curve minimum and maximum may be used to limit the output of the performance curve. curve = C1 + C2*x + C3*x**2 + C4*y + C5*y**2 + C6*x*y
