added variable reconstructed particle to GTreeManager. GTreeParticle is increasing or decreasing it if a particle is added or removed.
This will make the output sort a lot faster, cause one do not need to loop over all trees.
AddParticle in GTreeParticle is not inline anymore.
changed tree names for particles to pdg names. One can loop now over treeList and check if pdg name is corresponding to find a tree.
