Testing setup

[ghost]

Hi,

We've added basic test framework to the project (see wiki for further details). The test setup includes:

• jasmine for unit testing (running in the node environment)
• pointing our "test" script to the spec/unit/ folder and running and spec files contained within this directory
• code coverage (using Istanbul) for all unit tests: the coverage report is provided in the command line after running the tests, and also in the spec/coverage/ folder (which is currently .gitignored)
• travis.yml has been updated to include a node version (required to enable our dependencies to build correctly)
• we've included a selenium-standalone server and a webdriverio wrapper to support testing of our headless chrome browser for automated feature testing

connects to #9

Hi - I've added the reports folder to the .gitignore and removed these files from the project too
