Detailed Description

template<ContainerIdConcept CI = ContainerId::met, typename CM = ColumnarModeDefault>
struct columnar::MetHelpers::MetMomentumAccessors< CI, CM >

a special accessor for the MET momentum

MET has a somewhat special momentum structure, and the METMaker tool also needs to add to the momentum in a special way. So this class tries to provide a somewhat convenient and robust interface for that.
