Subject: Our new common template based start for Accessing and Manipulating

the Records
The CROSS_REFERENCE branch will get ported to it.
We use templates for several reasons
They allow us to share code and to be easily extended
I've to make them not inline to save memory...
I've to port all DBs and Record related classes
