                               | Some features are: 1.  It doesn't go belly up
                               | if it encounters a divide by zero or undefined
                               | result. 2.  It allows the domains of the XY
                               | plane to be defined to any value ( although it
                               | centers the plot on the origin). 3.  The
                               | equation is entered in X, Y, Z format not
                               | parametric form. 4.  It creates a matrix of
                               | the topology of the surface which is useful
                               | for locating actual values of a  max or min.
