Platform client

**NOTE**: This is dependent on https://github.com/tidepool-org/platform-client/pull/1

**NOTE**: This requires a `bower install`

Shows users that have added you to their care teams, so you can click on them and view their data and profile. For example, in this case I can now see Brandon:

To make this work:

- Create two accounts (continuing with above example, "Nicolas" and "Brandon"); A "patients" group should have been automatically created for both (after visiting the dashboard, which is the homepage anyway)
- Through the API or directly in Mongo, add Brandon's userid to Nicolas' "patients" group
- Nicolas can now see Brandon

I have more things I want to do (create groups on user account and patient profile creation, show care team members on my patient profile), but will be done as another PR in the interest of "iterative steps with functioning version at each".
