Gridmap plots

Gridmap plots produce a grid of orthogonal curves describing a function of a
complex variable of the form w =f(z) = f(x+iy), where z = x+iy is a complex
variable. The functions plotted correspond to the real and imaginary part of w
=
(x,y) + i (x,y), i.e., they represent curves
constant. For example, to produce a Gridmap plot for the function w = sin(z),
use the following:
