Phys/LoKiGen: add new symbols
"GMINTREE( GPT , 'mu+' == GABSID) > xxx * GeV"- it can mimic certains selection/tripping criteria and also
"GMINTREE( GPT , ( 'pi+' == GABSID ) | ( 'K+' == GABSID ) ) > xxx * GeV"- it mimics some popular stripping/Hlt2 cuts used by Charm and BnoC groups
"GMULTTREE( GPT , ( 'mu+' == GABSID ) ) > xxx * GeV * GeV "- it mimics L0DiMuon-TOS for eg. B-> ( J/psi -> mu mu ) X decays
They are useful to extend and simplify the syntax of
LoKi::GenCutTool allowing for mimic some trigger (e.g.
L0DiMuon) and/or stripping selection criteria (like scalar sum of Pt, massively used by Charm and BnoC working groups). It will allow to mimic certain selection/stripping/trigger criteria as tight generator-level cuts, drastically improving the overall performance of MC-production system.
