LoKiCore/LoKiMC/LoKiGen: "fix" the issue with inclusive&marked (MC&HepMC) decays
- "fix" the issue with inclusive&marked (MC&HepMC) decays
- add corresponding error code & disable creation of such trees via the factory
- provide viable alternative
- few MCINCLUSIVE functor/predicate
>>> get ( '/Event/MC/Particles' , MCINCLUSIVE ( 'Beauty' , 'Stable' ) )
- provide missing signatures for PARTICLE.child and PARTICLE.children (extremely useful for python)
- provide missing overloads for *Finder * (extremely useful in python)
