Continuous Integration with Travis CI

[mdoleh]

Travis CI can automatically run builds whenever a push is made to the GitHub repository. I've already setup the account and have it enabled for this project. We'll need to do the following to complete the setup:

• add a .travis.yml file to the repository
• add support for the "npm test" command into the project to run the unit tests via command line
• have a live host on HerokuApp that Travis CI can automatically push to on successful builds (optional)

Apparently this is more complicated than expected. After looking up solutions, it seems that integrating Karma is our best bet. karma supported compiling Typescript through a plugin and setting up the config file is no problem. However, Karma does not yet support the SystemJS module loader so it seems a hack is necessary to get around this issue which is more involved than I would have liked. I'm putting this on hold until Karma supports SystemJS natively. I do still want the HerokuApp live demo for this as it would be nice to have. I will look into it.
