We will extend client-side markup and rendering with javascript modules that can be installed by a site owner without additional rights, shared from owner to owner, and selected by the viewer when launching a tab. github 
pages/client-type-modules
We will test render these plugins now. You need to be viewing with Smallest Deployed and include a type library in the query portion of the url. example
Now a case study.
test cases

See Smallest Wiki Explained where we organize a whole site to match the organization of the code. We'll see how well this follows code refactoring.
