[WIP] CA: Cleaning up the MC information handling in the CA tracking steer class

This merge request separates tracking MC routines (performance, efficiencies, debug) from the steer tracking class (CbmL1). In particular, reading of MC information in event/TS is moved to a separate class - CbmCaMCModul. This class is accessible through CbmL1 and provides an interface to interact with MC information in tracking from CBM. The detector-independent classes (internal point and MC track containers, histogrammer etc.) are moved to the ca::tools namespace.

Fixed bug: index of tracking station in MC point selection for TOF
