Trait Extension 

pub trait Extension:
    Any
    + Send
    + Sync
    + Debug
    + 'static { }

Extension is type which can be stored inside an Extensions store

Currently this trait has no internal logic, but over time this might change and this might be extended to support more advanced use cases. For now this is still usefull because it shows all the Extensions we have grouped in the exported rust-docs.
