Multiple / Single background watchers behaviour #39

Hello, Thanks for the plug-in. I am using it for my app and is working as expected. I have few questions:

Should I add only one watcher and remove that watcher using watcher_id when user logs out? As I do not want location updates when user logs out.
when adding multiple watcher, does all of the watcher gets invoked when location is changed?
what is the lifecycle of watcher does it last indefinitely? If not how those watchers are removed?

Thanks. Kunal.

If you do not explicitly remove a watcher, the system will continue to deliver it location updates, which may cause unnecessary energy usage. Each watcher is independent, any component creating a watcher can ignore the existence of other watchers.

I forgot to mention: all watchers will be removed if the app is killed. They will not be re-added when the app is restarted.
