jet hypo: modify how jet groups are calculated in FastReducer when RepeatedConditions are present in the tree.
src/FastReducer.cxx, h create a table with ConditionMultiplicities: n identical Conditions are represented by a single RepeatedConiditon with multiplicity = n.
TrigHLTJetHypo/src/JetGroupProduct.cxx create a table with the passing jets (vector of indices) for each sibling node. The are n such entries in the table for each condition where n is teh mutliplicity of the condition.
