Detailed Description

a specialized accessor to read a selection decoration from/to an xAOD object

We have (at least) two conventions on how selection decorations can look like, the one from the CP algorithms/TAccept and the other from the derivation framework/overlap removal tool. This accessor is a base class with specific implementations for different conventions.

The actual interface has separate accessor functions for accessing as bitsets or as booleans. In part that is to avoid a lot of unnecessary back and forth conversions, but mostly it is to give us some more flexibility if we need to extend this in the future.
