0005  *
0006  *
0007  *  This class is an HLTFilter (-> EDFilter) implementing a basic HLT
0008  *  trigger for pairs of object, evaluating all pairs with the first
0009  *  object from collection 1, and the second object from collection 2,
0010  *  cutting on variables relating to their 4-momentum representations.
0011  *  The object collections are assumed to be outputs of HLTSinglet
0012  *  single-object-type filters so that the access is thorugh
0013  *  RefToBases and polymorphic.
