Allow running notbooks in binder

[bgctw]

Binder provides an environment to run Julia notebooks. However, a Project.toml with a julia compat entry is required to provide the Julia kernel with it.

Furthermore, Interactive.jl and plotly require further jupyter extensions.

Can you send a link so I can test this out?

Link to Binder with branch on forked repo I got using Interactive.jl working. I still had problems with the plotly() graphics backend. However, this allowed me running the tutorials after juliabox has retired.
