Detailed Description

Description: Categorization of different tt+xx processes, returning unique ID for each process as e.g. tt+bb, tt+b, tt+2b, tt+cc, ...

Implementation: 

The classification scheme returns an ID per event, and works as follows:

All jets in the following need to be in the acceptance as given by the config parameters |eta|, pt.
A c jet must contain at least one c hadron and should contain no b hadrons

First, b jets from top are identified, i.e. jets containing a b hadron from t->b decay
They are encoded in the ID as numberOfBjetsFromTop*100, i.e.
0xx: no b jets from top in acceptance
1xx: 1 b jet from top in acceptance
2xx: both b jets from top in acceptance

Then, b jets from W are identified, i.e. jets containing a b hadron from W->b decay
They are encoded in the ID as numberOfBjetsFromW*1000, i.e.
0xxx: no b jets from W in acceptance
1xxx: 1 b jet from W in acceptance
2xxx: 2 b jets from W in acceptance

Then, c jets from W are identified, i.e. jets containing a c hadron from W->c decay, but no b hadrons
They are encoded in the ID as numberOfCjetsFromW*10000, i.e.
0xxxx: no c jets from W in acceptance
1xxxx: 1 c jet from W in acceptance
2xxxx: 2 c jets from W in acceptance

From the remaining jets, the ID is formed based on the additional b jets (IDs x5x) and c jets (IDs x4x) in the following order:
x55: at least 2 additional b jets with at least two of them having >= 2 b hadrons in each
x54: at least 2 additional b jets with one of them having >= 2 b hadrons, the others having =1 b hadron
x53: at least 2 additional b jets with all having =1 b hadron
x52: exactly 1 additional b jet having >=2 b hadrons
x51: exactly 1 additional b jet having =1 b hadron
x45: at least 2 additional c jets with at least two of them having >= 2 c hadrons in each
x44: at least 2 additional c jets with one of them having >= 2 c hadrons, the others having =1 c hadron
x43: at least 2 additional c jets with all having =1 c hadron
x42: exactly 1 additional c jet having >=2 c hadrons
x41: exactly 1 additional c jet having =1 c hadron
x00: No additional b or c jet, i.e. only light flavour jets or no additional jets
