Class Description
- When a new Device is added the composer subscribes to its State changes.
- If it is not able to subscribe to events, then a polling thread is started. relays on PyTango_utils package to provide DynamicAttributes and DynamicStates. Either StatePolicy or DynamicStates property can be used to compose the State. StatePolicy uses the same format than Soleil`s composer, the default policy is generated the first time the composer is launched
