Find a way to handle / update / cache network information (network id, scores)

[aaronlevin]

#We don't have a good story for where the network information is stored:

• when rendering, it's helpful to know what network each node belongs to (for example, so we can draw circles around the sub-networks)
• certain actions can impact the network structure (e.g. destroyer, giver, clicking, etc.), so how or where do we persist that information (is clicking an action?)?
• If we persist the network as a separate object, how do we propagate new information when the network is updated or changed to the nodes who need to know what network they belong to for rendering?

Basically: need to figure out how to get the network information out of the main app and tracked into firebase, or decide explicitly not to do that and handle it in the browser (as it is now).
