WIP: improve the MCTruth handling in detector simulation

lintao@ihep.ac.cn requested to merge lintao/detsim/truth-of-secondary-calohit into master

Requests from Kaili and Yuexin:

  • need to separate the decay in tracker and calo
  • need to store the relation between hit and secondary particle

The tracks info: gamma -> e+e-
