[DGD] kotaka: new feature: object catalog

[Raymond Jennings]

Afraid it's not really anything more than an alternate namespace for objects.

I'm also thinking of allowing multiple catalogs to co-exist and have
the same objects listed in different ways.

Skotos already did this.

My guess is that they figured mud admins would get sick of referring
to objects by filename instead of more friendly categorizations.
Ditto for referring to clones by number.

It would probably require runtime interpretation of inherit directives.

The kernel library presently does not allow this as far as I know.  If
anyone knows different, correct me.
