Abstract base class for control devices. Subclasses will provide
functionality to query capabilities and register <a class="link" href="BtIcControl.html" title="BtIcControl"><span class="type">BtIcControl</span></a> instances.
They will also read from the device and trigger the change events on their
controls (via value property).

This baseclass manages the added controls. The can be queries by calling
