class DeformedDataSource from MeshVS inherits DataSource from MeshVS

	---Purpose: The class provides default class which helps to represent node displacements by deformed mesh
        --    This class has an internal handle to canonical non-deformed mesh data source and
        -- map of displacement vectors. The displacement can be magnified to useful size.
        -- All methods is implemented with calling the corresponding methods of non-deformed data source.
