* Convert build to use a single JavaScript file on the site (instead of downloading each library separately). This also means that all global variables (e.g., `$` for JQuery, `_` for Underscore.js) can be removed. * Remove unused scripts and/or move them to a more appropriate repo * Update the `deploy` script to work with CircleCI's automation * Update markdown display code to allow images to be located with the markdown data files instead of the pre-rendered index pages
