Subject: [PATCH] Script to convert existing models to binary. Found a curious
 thing: taking one very complex file from ascii to binary increased the file
 size dramatically (9460%). Need to investigate if this was a specific case
 and whether or not this is something to investigate in other projects. The
 model in question is gnal_100ft_spiral_top.stl produced by current code.
