class BasicMsgRegistrator from ShapeExtend inherits TShared from MMgt

    ---Purpose: Abstract class that can be used for attaching messages
    --          to the objects (e.g. shapes).
    --          It is used by ShapeHealing algorithms to attach a message
    --          describing encountered case (e.g. removing small edge from
    --          a wire).
    --
    --          The methods of this class are empty and redefined, for instance,
    --          in the classes for Data Exchange processors for attaching
    --          messages to interface file entities or CAS.CADE shapes.
