First commit of the repo!

Additions:

1. After some quick learning, began writing the task code in
tasks/spinel.js. Currently it can:
   a. Read some basic options
   b. Get all of the files specified in the options
      i. It checks for user-defined CDN and local paths and will look up
      the CDN paths of known frameworks (e.g. Mocha)
   c. Opens the HTML files and can find the <head> tags

TODO:

1. Add <script> and <link> tags to HTML files if they don't exist
