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.
Returning a generic would allow for
List<ExtensionElement> list = stanza.getExtension("foo", "bar");
to compile (Note the we are calling getExtension(), not
getExtension*s*()).
Users are encouraged to use the type safe getExtension(Class<? extends
ExtensionElement) variant instead.
Fixes SMACK-825.
XEP-0080 states that lon,lat,error,alt,accuracy,bearing and speed are
decimal values, and thus should either be present as decimal, or not present
at all (as they are optional elements).
Usage of String.valueOf(value) in code lead to creating a "null"
string in case number was not present, thus creating an element with
"null" content, which is not a valid decimal value.
