Write a section on setting up a new control repository

[smashwilson]

The process for setting up a new control repository involves setting up an npm package, Grunt, and including the asset plugin, as well as writing the content and template mapping files. You can do anything with the build that grunt lets you do, of course, but it would be good to have a basic starting place that you can copy-and-paste.

For that matter, automating it would be a good idea...
