Offline Web App for Laptop Use

[roshanr10]

Prerequisite: #11

As part of our laptop data input and analysis application, I’d like for it to be able to work offline using a HTML5 LocalStorage Cache and posting data when reconnected, either manually or automated via a polling mechanism.

I think ServiceWorkers may work for this as App Cache is being phased out, but that needs more research.

Subtasks:

• [x] Decide Caching System
• [x] Implement Base Code for Both
• [x] Cache input data when offline
• [x] Send cached input data when online
• [x] Store processed data when online

@fimmel what do you think we should do for laptop use?

It's definitely easier if we go w/ network only, but then we can't go to other stands, like how you mentioned WPI

PouchDB take's care of all caching and syncing, except for the BT bridge between tablet and Pi.
