'''
A Track object loads the appropriate preprocessed data based on a track name.
Calling the method getTrackView gives an object (really of class TrackView) that is used simply to iterate through all track elements of the given genome region.
A track element (of class TrackElement) has methods start,end,val,strand. Some of these will typically be None, depending on the format of the requested track (e.g. for Segments the method val will return None..)
