Detailed Description

Specialised class for browsing xAOD event interface objects in ROOT

In order to read xAOD interface objects/containers correctly, one needs to use the xAOD::TEvent class. Since the regular ROOT classes can't be taught how to use an external object for reading information, we need to do it using inheritance.

The design was pretty much stolen from the AthenaROOTAccess code. Luckily in this case the code can be a lot easier. Here we just need to ask the TEvent object for the correct pointer, and we're done.
