A layer provides a convenient interface to control resources. In a layer, you can group several controls by name. The layer itself is an exclusive resource. When grabbing the layer, it will try to grab all controls and will forward them to its own owner when he receives them, and will take them from him when they are release. The layer with give and take away the controls from its client using methods of the form:

   client.set[control-name](control)

Where [control-name] is the name the control was given in this layer. This way, layers are a convenient way to provide controls to components indirectly, with automatic handling of competition for them.
