my_new_personal_website-8698a276f937cb1cd6f67f7f213e2ea438500d7e.zip
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.

+ *
+ * Modernizr will also add classes to the <html> element of the page,
+ * one for each feature it detects. If the UA supports it, a class
+ * like "cssgradients" will be added. If not, the class name will be
+ * "no-cssgradients". This allows for simple if-conditionals in your
+ * CSS, giving you fine control over the look & feel of your website.
