No it doesn't. It only verifies that the pipes stay in the containing box
(they tend to crawl on the box surface after a while). Implementing collision
detection shouldn't be to difficult (though parsing intensive) since the path
of the pipe is kept in an array, but the macro was primarily built to create
automatically a very complicated pipe object that looks good with no intention
of verisimilitude whatsoever. Indeed, these pipes look much better when they
cross... I decided to write the macro after trying to position the pipes by
hand (and having little success).
