[OctDev] bwlabeln "finished"

[Jordi G. H. <jo...@oc...>]

I've done a few fixes to bwlabeln in svn so that

    1) it doesn't segfault (or at least I couldn't devise a test that
made it segfault)
    2) It has a help text
    3) it errors out gracefully
    4) it actually does what it's supposed to

Sadly, it's slow. :-( But fast enough fo rmy purposes. I would
appreciate if anyone who cares about 3d images could test it.

I am therefore considering this done, and I will be doing a release of
the image package soon. For my purposes, I need to remove a few
unnecessary trivial checks for two-dimensionality in regionprops.

Comments?
