Possible to have a simple Binder instance (for Jupyter notebooks)?

If possible, it'd be nice to have a simple Binder instance to toy around with some examples for code.

I think it's just an apt install of castxml, then pip install of pygccxml, which seems like it'd be pretty straightforward? Here's an example for our project: https://github.com/RobotLocomotion/drake/tree/8dad68e1bacd4e79405835e961f80ba0826c6667/.binder
