An Architecture for a hardware-software system II

This is our solution at Tonbo Imaging to the question I put up here.

Very broadly, I'll break our solution into:

1. The various components and gluing them together
A whole lot of Managers that handle various aspects of the software, the Views, a CommandParser, and MessageResponse Queue, all glued together by an internal RxBus - asynchronously sending messages from various threads to one another.

2. Device Capabilities + Autogen UI
Each camera broadcasts its capabilities, a json file containing a list of commands it can take. Each command contains its parameters, their datatypes and the list/range of values they can take. A lot of the UI is autogenerated from this.

3. Versioning
This was fairly tricky and we're still not 100% sure we're happy with what we have. We have to take care of the versioning between various components:
- camera OS ⇌ camera software
- camera software ⇌ clients
- camera software ⇌ web

4. Camera-Graphics-Display-Streaming 
I'll add the graphics librar…
