This place holder is called the Tool Host Control, and is created by this method. When ShowTool(Type, String) is called, the Tool Control will automatically be added to the Tool host Control. Each host has an identity which makes it possible to find it using FindToolHost(String) Add the returned control to the Controls collection of the browser Tool Window.
The Tool Control itself will be added to the Controls collection of the Tool Host Control, by the manager when ShowTool(Type, String) is called.

If there is a host visible, that has been registered to host the specified Tool Control, the control will be instantiated and shown. The current Tool Control of the host (if any) will be closed.
