better handling of displays with pleasantness colors

+function cmap = randomColormap (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
