Cleaned out public from repository, updated gitignore, added syntax
highlighting tests, improved syntax highlighting and styling of pre blocks. Overriding dynamic gist styling. Added a plugin for pygments caching which should speed things up terrifically. added ender.js as a lightweight way of scripting the DOM, events, etc. Some general typography and semantic html improvements.
