Description
https://github.com/openedx/edx-platform/blob/kdmccormick/extension-points-doc/docs/concepts/extension_points.rst is a related doc that may point to other examples we want to implement. Review the doc and ticket up any specifics we want to implement here.
At a glance, we definitly want to have an example of an xblock here. Whether it's part of the existing plugin and another top-level folder/python library is TBD.
