returns mutable Selection from AIS;
---Purpose: creates a new selection and make it current in the session.
-- the selection will be accessible later through its name
-- to make it again current.
--
-- Note that if a session has been created, a session with
-- the name "default" is created.
--
-- In this case, the is always a current selection which
-- is the last one created until SetCurrentSelection is used.
--
-- The class methods deals with the current selection.
--
-- Warning : Better Call AIS_Selection::CreateSelection.

CreateSelection(myclass;aName:CString from Standard)
returns Boolean from Standard;
---Purpose: calls the private constructor and puts the new Selection
-- in the list of existing selections.
-- returns False if the selection exists.

---Purpose: if the object is not yet in the current selection, it will be added.
-- if the object is already in the current selection, it will be removed.
AddSelect(myclass; anObject: Transient from Standard)
returns SelectStatus from AIS;
---Purpose: the object is always add int the selection.

ClearAndSelect(myclass; anObject: Transient from Standard);
---Purpose: clears the selection and adds the object in the selection.
