Change Details

* Really just showing the mechanics. I haven't put much thought into the actual (to be generated) extension code beyond what is in the comments. * Needs us to decide on our API builder facility to get much further (i.e. builder objects, with blocks, etc).

* Still rough edges that need more sugar but the bones are there. Notes left in the test case for things that can be improved. * Does not actually yield custom OpViews yet for traversing. Will rework that in a followup.
