Detailed Description

The central user class to manipulate any global constant in any DB object Used to retrieve global parameters from database and access the for update.

Finally all objects can be released for storing in the DB. NOTE the objects are not constructed (an thus quite some memory is saved) until you access them. But the monitoring of changes in DB starts since addDBObj<...>() TODO correct constness to not construct on listGlobalParams()
