 Create a JSFVertexing object for finding and fitting of a vertex
 consisting of ntracks tracks.

 Clear JSFHelicalTrack objects saved in fT.

 Stores JSFHelicalTrack objects for vertex finding and fitting.
 id is a location where JSFHelicalTrack object is stored.
 It should be a number from 0 to fEntries-1 ( nTracks-1 ).
