== BTagging ==

determines origin of jet, applies b-tagging efficiency (miss identification rate) formulas and sets b-tagging flags

 - input:
  - !PartonInputArray
  - !JetInputArray

 - output:
  - !OutputArray

 - parameters:
  - DeltaR
  - PartonPTMin
  - !PartonEtaMax
  - !EfficiencyFormula - efficiency (miss identification rate) specified for a PDG code as a function of transverse momentum and pseudo-rapidity 
  - BitNumber (default 0)

Starting from version 3.0.7 it is possible to test several (up to 32) b-tagging working points for every jet.
The BTag variable in the Jet class can store up to 32 bits. If the user specifies BitNumber = 0 in the BTagging module, that particular bit will be stored in the first position.
If BitNumber = 1, it will be in the second position, etc ...

In order to check whether a jet has passed the b-tagging criterium defined by the BitNumber = i,  just do:
