Tree (and other 'Container' components)
'Container' components are a means to hierarchically structure the application in the nE2 controllers.
The "Tree" is a special component which represents the root of the nE2 application.
The "Tree" is added automatically under the nE2DeviceExt after the application is successfully loaded.
