Minor tweaks to the AsgxAODNTupleMakerAlg
This MR adds minor tweaks to the AsgxAODNTupleMakerAlg
. It's mainly meant to be an intermediate solution until we make the algorithm more robust.
Changes:
- allow duplicate output definitions (needed for systematics decorations)
- when adding a branch one can allow missing aux item
- return an error if a rule can not create any branch
@akraszna should review this, also notifying @krumnack, @jburr, @khoo
