This file provides a couple metafunctions that can be used to select the proper pool converter class for a given data object.

xAODInterfaceSupportingThinning<T>() evaluates to true if T is an xAOD interface class (DataVector or standalone) that has not been tagged with supportsThinning = false. xAODStoreSupportingThinning() is the same for xAOD auxiliary store objects.
