Programmability Update 2

The second programming update adds a number of new features and blueprints that expands the capabilities of the graph programming system. We are adding the following new nodes to expand on the logic:

• Variable node: allows storing information across frames

• Timer node: allows programs to be time aware

• Individually programmed motors / pistons: dynamically and separately control each motor

• File node: reads a json array for more complex logic

We are also adding 2 new blueprints to showcase these features: "stopwatch", which is a mechanical digits display, and "piano bot", which takes advantage of the new "import" feature to automate a previously built piano.
