FirebaseDatabaseDataManager class

Stores CARP json objects in the Firebase Database.

Every time a CARP json data object is created, it is uploaded to Firebase. Hence, this interface only works when the device is online. If offline data storage and forward is needed, use the FirebaseStorageDataManager instead.
