Ready for Beta, again

We went back to alpha to redesign the way tables were implemented. That's been done--the rows in a table are now LSecs.

The sample application, simple accounting, is also working. And the code is a whole lot better than when tables were implemented as document content.

So we're ready for beta. Things are looking reasonably stable. But it is a very early beta. We need documentation on descriptor units and on the simple accounting application. As well, it is an awkward Wiki to use. Much work remains even to regain the capabilities of its prototype, AgileWiki2.
