Make use of pep instead of pubsub in GeoLocationManager

This mini assignment kicked-off with replacing `pubsub` with `pep`,
but later transformed into something more.

The alterations and additions in this commit:
 a) GeoLocation.
    1) Add Documentation.
    2) Add `EMPTY_GEO_LOCATION` to be used while
       `stopPublishingGeoLocation()` is called.
 b) Add GeoLocation IntegrationTest.
 c) Add GeoLocation Listener.
 d) GeoLocationManager.
    1) Add Documentation.
    2) Replace `pubsub` with `pep`.
    3) Add methods to add-and-remove GeoLocationListeners.
    4) Enable GeoLocation by default.
 e) Add `package.info` for GeoLocation Integration Test.
