package TopLoc 

    ---Level : Public. 
    --  All methods of all  classes will be public.

    ---Purpose: The TopLoc package gives ressources to handle 3D local
    --          coordinate systems called Locations.
    --          
    --          A Location  is a composition of  elementary coordinate
    --          systems,  each one is  called a  Datum.   The Location
    --          keeps track of  this composition.
    --
