Detailed Description
CloudToSimTrackerHitProcessor: This processor takes as input a collection of TPCElectronClouds and returns a collection of SimTrackerHits.
This collection can be used e.g. by the digitisation/GEMProcessor. In order to convert the TPCCloud into SimTrackerHits the longitudinal and transverse diffusion of the cloud is used to distibute the electrons of the cloud randomly (gaus). Thus a cloud with n electrons results on n SimTrackerHits with EDep of the ionisation energy of the drift gas. The default corresponds to the ionization energy of Ar. It is also possible to create only one SimTrackerHit for each cloud with EDep=n*2.6e-08. The drift velocity is needed to calculate the time step after the z step corresponding to the longitudinal diffusion was set. //TODO: change this to be used with other gases
