Implement testing framework

[jasonlally]

Based on some more research, the best testing pattern for React appears to be:

Karma + Mocha + Webpack (already using) + Istanbul for code coverage

Then in the future we can integrate with a Continuous Integration platform and if we want to get real fancy look into BrowserStack or SauceLabs for robust cross platform tests. I believe we have access to SauceLabs through C9, but maybe not the full testing suite.

This is somewhat implemented, but I think we need to write a couple of tests and make sure the infrastructure is working

So, I think I'm just about there, but I cannot seem to figure out where I'm going wrong with this error when running karma start:
