account creation

http://agilewiki.wiki.sourceforge.net/AccountCreation

Good progress today--got account creation working and wrote the guide. (See the link above.)

The code got interesting. The createAccount operation required that, in the middle of processing a transaction on one database, a query must be run against the master database. It went fine, but I've got a feeling that we need to have some means of returning an error message.

I also ran into some problems doing a query. The culprit was immutable name which now works in a query so long as the name was already immutable.

Now what I am particularly happy about is that the new code is making good use of a lot of COODBMS features. So a lot more code is being exercised. And the few problems coming up are very minor.
