## Summary: ContextType is in use at Khan as a part of our ka-context system; it basically just lets you configure the type to pass as the `ctx` argument to genqlient helpers (or say to omit such an argument). ClientGetter I wrote thinking we might use it; then we didn't (because we have a few different clients we may use) but it's not much code and may be helpful to others. In this commit I clean up, document, and add tests for both options. The cleanup is mainly for ClientGetter, which was kind of broken before because it was a Go snippet but couldn't specify imports. I was thinking maybe you want to be able to write `ctx.Something()`, but I just don't see how to make it work, so I made it a function of context, which is probably the better idea anyway. Additionally, I improved the documentation for both, and added tests for those and several other config options that weren't completely tested. Fixes #5.
