Detailed Description

Helper to save conditions pools to ROOT.

This is a rathr simplistic persistency mechanism for conditions. It is not suited to actually store and retrieve individual conditions by key. Though it is rather efficient to store and retrive entire conditions snapshots of the conditions store implemented by DDCond. It e.g. allows to fast load the conditions store for HLT applications, of which we know it takes ages to populate it from a database.
