The large TeljesPanorama class has been divided to 3:
- Grid: contains the fitting and navitgation in the image grid
- TopLevelModel: top level interface to the panorama extension and
manipulation
- TeljesPanorama: an extended hsi.Panorama object. It adds image,
creates control points and sets image parameters for easy panorama
handling. The images to be added lack identifyable  structure such as
corners or edges, so arbitrary positions in an image are transformed to
the panorama coordinate space and then transformed to the other image.
So control point finders would not find this CPs. The fitting is not
improved. However the whole panorama can be moved, straighened etc in
hugin
