LHCBGAUSS-911: Updates to the EvtFlatQ2 EvtGen model for B to X lepton lepton decays The EvtFlatQ2 model has been extended to work for any B to X lepton lepton decays to generate a flat q2 distribution (for detector efficiency studies). It also includes a phase space correction to make the distribution flat in the low q2 kinematic region. This will also be suitable for the master branch. See merge request !45

Jiraticket 657, Improve ImpactParam_PERIPH.py option file (related to LHCBGAUSS-657 and LHCBGAUSS-894) * To be propagated to master and Sim09 branches * Improvements have been made in the ImpactParam_PERIPH.py option files which purpose is to define centrality cuts in EPOS for PbPb. * Those changes have been made to account for all possible configurations of EPOS which have been deployed in the new EPOS.py file (see LHCBGAUSS-894) See merge request !42

New EPOS option file Add new EPOS.py generic option file in Gen/LbCRMC which creates automatically the correct configuration for EPOS based on: - beam momentum to define the fixed target or collisionner mode - event type to generated minimum bias events or to embed Pythia8 signal events with EPOS underlying event See merge request !35

This model now works for all B -> X lepton lepton modes. The extra phase space factor (courtesy of Marcin Chrzaszcz & Thomas Blake) is enabled by using "FLATQ2 1" instead of just "FLATQ2" in the decay file.

LHCBGAUSS-841: Modifications to EvtTauolaEngine for the B to tau tau physics analysis Code changes to `EvtTauolaEngine` in EvtGen to allow the B to tau tau physics analysis to move forward: 1) It uses the updated BaBar hadronic currents by default. An extra decay file keyword `TauolaCurrentOption` can be used to reset the integer value via `Tauola::setNewCurrents()`. This means that if there is a build of Tauola with the intricate CLEO currents enabled, then the code will be able to use that by setting `Define TauolaCurrentOption -1` in the decay file. 2) The code also allows the option to set the sub-branching fractions of certain modes via `Tauola::setTaukle`, which will improve MC generation efficiency by ignoring unneeded modes, using the decay file keywords `TauolaBRx`, where x = 1,2,3 or 4. 3) It also contains some code to artificially set the PDG ids of the tau parents to vector bosons to use internal Tauola spin matrix weights, but this is not enabled by default, since we believe it doesn't do the right spin physics for B decays (we need further feedback from the Tauola developers). 4) There is also new code in `EvtParticle` to allow the future storage and retrieval of double quantities, such as amplitude weights, via the `setAttributeDouble(name, value)` and `value = getAttributeDouble(name)` functions, although no decay model is using this at the moment and will therefore have zero effect on current MC production. This code will be suitable for both the Sim09 and master branches. See merge request !28
