function cmap = generateColormap (sceneObjects)
% returns a colormap with randomly chosen colors somewhat evenly spread in
% the color spectrum, to be used for the graphical representations of a
% synthesized scene.

% Background sounds will have a saturation of .3, foreground sounds of 1
% Value is always let to .5, since modifying it would erroneously suggest
% a difference of intensity
