Tutorial: breakout board

[jonnew]

I want to get one solid tutorial together that can be used as a basis for the rest. The breakout board is the proposed target. The reason being that all onix users will have one and it will demonstrate the usage pattern that will be extended to other devices. The tutorial should be aimed at practical usability and include the following elements

• A workflow that showcases every major feature of the breakout board
• A breakdown of the workflow into logical elements with descriptions of what they do and how they can be changed
• Data saving
• Data loading scripts.
