<｜begin▁of▁sentence｜>### Instruction:
Assuming you have custom classes for drawing shapes like 'CircleDrawer' and 'SquareDrawer', how would you register these classes into the ShapeDrawerDirectory so they can be used within a system that relies on this directory?
### Response:
from ShapeDrawerDirectory import ShapeDrawerDirectory

# Suppose you have a namespace with custom shape drawer classes
custom_shape_drawers = {
    'CircleDrawer': CircleDrawer,
    'SquareDrawer': SquareDrawer
}

# Register all custom shape drawer classes in the namespace
ShapeDrawerDirectory.register_namespace(custom_shape_drawers)
