Anti-Tau decoration in channel-depends way
The anti-tau decorated in EasyjetHub/src/TauDecoratorAlg.cxx
should be updated to create only up to 2 anti-taus, and in different way in lephad/hadhad channel.
First the number of well-identified taus should be checked.
In lephad channel, if well-ID tau is not there, 1 anti-tau should be selected.
In hadhad channel, if number of the well-ID tau is 0(1), then 2(1) anti-taus should be selected.
The way of selecting anti-tau needs to be checked; it should be selected randomly or just choose the first one (lead-pT one ) ?
Also the trigger-matching will need to be added ultimately.
