10                         This method gets called when the service daemon
11                         unregisters the counter. A counter can use it to do
12                         cleanup tasks. There is no need to unregister the
13                         counter, because when this method gets called it has
14                         already been unregistered.

18                         This signal indicates a change in the counter values
19                         for the service object. The counter is reset by calling
20                         the service ResetCounters method.
21
22                         When registering a new counter this method will be
23                         called once with all details for "home" and "roaming"
24                         counters filled in. Every further method call will
25                         only include the changed values.
26
27                         When "home" counter is active, then "roaming" counter
28                         will contain an empty dictionary and vise-versa.
