Template track finder

The template track finder implemented in cmsim10x consists of two basic parts: hit preselector (steered by tfmake) and track finder/fit (steered by tfapply). The preselecting part is simplified: for each mc track it prepares a single 'template' which in the simplest case is just a list of all detectors hit by this track. The track finder/fit is based on a 3D Kalman filter and uses GEANE as a track/error propagator which makes it completely geometry independent.

The template track finder is selected with RECO 'TRAK' set to 2 or 12. For option 2 it tries to reconstruct all 'good' tracks (charged particles with ); option 12 means reconstruction of one track (having mc number 1). The list of considered and reconstructed tracks can be printed out with DBUG 'TRAK' 1
