1. service decorator was overwriting the function name with one of its
arguments.
2. Accidentally left an extra argument in track_sunrise.
3. Added track_utc_time_change decorator.
1. Added HASS to the arguments for callbacks that are created with
event decorators.
2. Added a service decorator.
3. Updated example.py in the example config to use the event decorators.
This revision of event decorators removes much of the complexity. The
decorated functions are no longer wrapped with a class that tracks
last_run, etc. Bootstrap now gives hass to the event_decorators module
before initializing components so the decorators no longer require
activation.
Created event decorators for custom components. Decorators were created
for the events: track_state_change, track_sunrise, track_sunset, and
track_time_change.
