Implement Dolphin

Project Member Reported by tby@google.com, Jan 14 
We would like to implement a general recurrence ranker, named
Dolphin, for generating recommendations based on a user's past
actions. We plan for Dolphin to be the backend for other search
and ranking projects, eg. the file ranker. 

This will generalise the existing app launch predictor.

Design doc: go/dolphin-design-doc

[Dolphin] Implemented the frecency store.

Begun work on the recurrence ranker (go/dolphin-design-doc), which
generalises the app launch predictor to be useful for other tasks.

This CL adds the FrecencyStore class, which is the core data structure
of the new system.
