-//The purpose of this class is to permorm the ITS tracking.
-//
-// The constructor has the task to inizialize some private members.
-// The method DoTracking is written to be called by a macro. It gets the event
-// number, the minimum and maximum order number of TPC tracks that are to be
-// tracked trough the ITS, and the file where the recpoints are registered.
-//
-// The method AliiTStracking is a recursive function that performs the
-// tracking trough the ITS
-//
-// The method Intersection found the layer, ladder and detector where the
-// intersection take place and caluclate the cohordinates of this
-// intersection. It returns an integer that is 0 if the intersection has
-// been found successfully.
-//
-// The two mwthods Kalmanfilter and kalmanfiltervert operate the
-// kalmanfilter without and with the verteximposition respectively.
