Add bipartite network component

[asizemore]

For the mbio correlation app

So i think we'll need a BipartiteNetwork component, possibly also a Network component as well? Definitely a NodeWithLabel component.

See doc for all the new types and data expected.

Steps:

• [ ] Define types
• [ ] Create NodeWithLabel
• [ ] Create Network
• [ ] (maybe pause for review?)
• [ ] Create BipartiteNetwork

For later:

• handle clicking nodes (in component? bc they have to get highlighted...) highlighting
• handle clicking nodes reordering (in viz or component? i guess component)
