Added a "/:user/recent_pushes" route to return metrics on modified JavaScript files within a user's last n (10 by default) push events.
Augmented the retrieval of developer file metrics so that, by default, all possible push events from the GitHub server are analyzed.
Modified "/:user/commit_metrics" route to serve up an array of commits, rather than an array of pushes with commits.
Added Parse.com Node.js dependency.
Added in Parse initialization. Also corrected issue with Parse module require statement.
