//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.
