 **File naming** - Since contexts export both consumer and provider (and potentially in withContext function form), the file can be simplified to be named after the consumer export.  In other words, the file containing the `Network` context components would be named `Network.jsx`.

+**Component naming and conventions** - In order to provide a consistent interface with react-router and [lingui](https://lingui.js.org/), as well as make their usage easier and less verbose, context components follow these conventions:
 - Providers are wrapped in a component in the `FooProvider` format.
   - The value prop of the provider should be pulled from state.  This is recommended by the react docs, [here](https://reactjs.org/docs/context.html#caveats).
   - The provider should also be able to accept its value by prop for testing.

 const config = {
