Update devices in UI dynamically

[ddellacosta]

I need a comprehensive system to update devices in the UI given the current state of devices on the network.

Acceptance Criteria

• must be responsive enough that updates are registered without any noticeable lag or slowdown of the UI

Technical Notes

• maybe every state update (or subsets of state updates) should be treated as a delta, and if no change is computed it shouldn't update the device state? This sounds awfully like the existing React update algorithm...am I doing extra work here somehow?
• do I need to retain prior state? I don't think so. Every state update can simply overwrite the value mapped to a given device
• should I store deltas based on the specific protocol data I get vs. an abstracted version of that data? I think I'll need to address figure out data model for device before I can tackle this.
