starting to add DiTauRecTools package for DiTau studies
This MR is meant to add a new package called "DiTauRecTools", meant to collect all the tools to study/provide info about DiTau objects (similarly to what's done by tauRecTools for standard taus)
The package now contains two piece of code migrated from R21:
- IDVarCalculator -> meant to add additional information to the DiTau
- DiTauDiscriminant -> meant to evaluate a BDT score for DiTau identification
both parts of code have been used for boosted bbtautau analysis in R21 and we would like to make the tools available also in R22 and available for other analyses as well
Long term plan would be add the BDT score/some variables in DAOD PHYS, but as first implementation the tools can be scheduled like other CP tools in ABR and used -> this was tested using xTauFramework (used for TauCP T&P analysis) + DAOD PHYS
