% function AddHullToTrack(hullID,trackID,previousHullID)
%The hullID will be added to the track
%
%If trackID is given, previousHullID is not used.  Safe to
%send [] for either trackID or previousHullID.
%Prereq to leave trackID empty - Track to be added to exists and the
%previousHullID exists in that track.  Also, it has been
%removed from any previous track assosiation.
