My intention was to add this method in addition to `public static ContentObserver getContentObserver(Account account, String authority)` (and maybe add a simple proxy for `unregisterContentObserver()` as well) so the user could call it like this:
```java
this.contentObserver = sprinkles.getContentObserver(getSyncUser(), AuthConstants.CONTENT_AUTHORITY);
sprinkles.registerContentObserver(Note.class, true, this.contentObserver);
```
and could unregister like this:
```java
sprinkles.unregisterContentObserver(this.contentObserver);
```
