"""
Register the ryu application specified by 'service' as
a provider of events defined in the calling module.
If an application being loaded consumes events (in the sense of
set_ev_cls) provided by the 'service' application, the latter
application will be automatically loaded.
This mechanism is used to e.g. automatically start ofp_handler if
there are applications consuming OFP events.
