Use CoreML Recommender for sorting contacts

[rabble]

Everywhere we list people, we should use the CoreML Recommender algorithm to sort the list based on recommendations.

iOS supports on device machine learning. We can generate a model which will suggest what contacts the current user are likely to want to follow based on other users. This is much better than the current way of just sorting alphabetical.

Use Create ML to create it, and then generate the ML to be used for listing results. This should be used for the directory and profiles.

Contact @rabble if you need more information on setting it up.
