"""Returns the progress of the learners - the explorations and collections

Args:
user_id: str. The id of the learner.
Returns:
(LearnerProgress, dict, list(str)). The first return value is the
learner progress domain object corresponding to the particular
learner. The second return value is the numbers of the activities
that are no longer present. It contains four keys:
- incomplete_explorations: int. The number of incomplete
explorations no longer present.
- incomplete_collections: int. The number of incomplete collections
no longer present.
- completed_explorations: int. The number of completed explorations
no longer present.
- completed_collections: int. The number of completed collections no
longer present.
The third return value is the titles of the collections to which new
explorations have been added.
