// AliTPC parallel tracker
+//
+// The track fitting is based on Kalaman filtering approach
+
+// The track finding steps:
+// 1. Seeding - with and without vertex constraint
+// - seeding with vertex constain done at first n^2 proble
+// - seeding without vertex constraint n^3 problem
+// 2. Tracking - follow prolongation road - find cluster - update kalman track
+
+// The seeding and tracking is repeated several times, in different seeding region.
+// This approach enables to find the track which cannot be seeded in some region of TPC
+// This can happen because of low momenta (track do not reach outer radius), or track is currently in the ded region between sectors, or the track is for the moment overlapped with other track (seed quality is poor) ...
+
+// With this approach we reach almost 100 % efficiency also for high occupancy events.
+// (If the seeding efficiency in a region is about 90 % than with logical or of several
+// regions we will reach 100% (in theory - supposing independence)
+
+// Repeating several seeding - tracking procedures some of the tracks can be find
+// several times.
+
+// The procedures to remove multi find tacks are impremented:
+// RemoveUsed2 - fast procedure n problem -
+// Algorithm - Sorting tracks according quality
+// remove tracks with some shared fraction
+// Sharing in respect to all tacks
+// Signing clusters in gold region
+// FindSplitted - slower algorithm n^2
+// Sort the tracks according quality
+// Loop over pair of tracks
+// If overlap with other track bigger than threshold - remove track
+//
+// FindCurling - Finds the pair of tracks which are curling
+// - About 10% of tracks can be find with this procedure
+// The combinatorial background is too big to be used in High
+// multiplicity environment
+// - n^2 problem - Slow procedure - currently it is disabled because of
+// low efficiency
+//
+// The number of splitted tracks can be reduced disabling the sharing of the cluster.
+// tpcRecoParam-> SetClusterSharing(kFALSE);
+// IT IS HIGHLY non recomended to use it in high flux enviroonment
+// Even using this switch some tracks can be found more than once
+// (because of multiple seeding and low quality tracks which will not cross full chamber)
+//
+//
+// The tracker itself can be debugged - the information about tracks can be stored in several // phases of the reconstruction
+// To enable storage of the TPC tracks in the ESD friend track
+// use AliTPCReconstructor::SetStreamLevel(n); where nis bigger 0
+//
+// The debug level - different procedure produce tree for numerical debugging
+// To enable them set AliTPCReconstructor::SetStreamLevel(n); where nis bigger 1
