most samples are converted, a spot of writing

A bit of a grind today, but I've converted all but two of the COODBMS sample programs as well as flushing out the RoleML script interpreter and the DRM. The samples should be done tomorrow.

I've also done a bit of writing: http://agilewiki.wiki.sourceforge.net/ Yeah, its only a start and I find I keep covering basically the same ideas. But I need to get it right, get everything in proper perspective and improve the overall clarity.
