Initialize a package.json descriptor for npm modules
Configure testing environment

After a lot of thought I've decided to use Karma with Jasmine and
karma-bro to run my unit tests on PhantomJS. I was also looking into
TAP, tape and testling, but the lack of good reporters for Windows
combined with the fact that the syntax of the tests looks a tad bit
funky discouraged me from using it in this project as of now.

Furthermore, as this is primarily a front end repository, tests
concerning browserify and other browsers seem imminent when dealing
with renderers, so there isn't that much of a stimulus to run the tests
on just node, saving the extra steps of bundling and launching a
headless browser in the background.
