COODBMS basics are working, finally

It is after midnight here, but I've finally got the basic structures of COODBMS working. (I'll work on the releases for CowDb and COODBMS tomorrow.) I've been very close for some time, but now it is both working and clean. And I am quite happy with the result.

This leaves only calendar sections (and a tad bit more documentaton) before moving on to JOODBMS. So expect some posts on JOODBMS. Hopefully it will kick off a lot easier than did COODBMS.
