Revision of the ALICE TRD tracking code

Its performance has immediate influence on other reconstruction tasks such as calibration, alignment and particle identification. The tracking algorithm is designed to work with or without prior estimate of the track position. Thus one can distinguish two main applications: the Stand Alone Tracking (SAT) used in the High Level Trigger (HLT) system of ALICE or to analyze test beam or cosmic rays data and the Standard Tracking (ST) used to reconstruct physics events in the ALICE offline framework.
