Gesture recognizer for the Pebble Time:

iOS app controller:

• The Pebble app contains the gesture recognizer and accelerometer controller, implemented in pure C using Basalt/Pebble SDK v3.
• The iOS app is linked to the Pebble app, and consumes incoming gesture results to control the phone, post updates to IFTTT via the feed server, and make payments via the payment server.
• The feed server allows users to subscribe to gestures using IFTTT via per-user RSS feeds - the app posts updates to the feed server, which updates the user's feed.
• The payment server handles payments via BrainTree, processing transactions made from the iOS app.
