Basic working functionality

This first pre-release has achieved the initial goal of passing the original tests for semi-complex CSS selector translation.

There are some edge cases to work through and when more complex tests are written we will surely find some room for improvement, but for now this is 233 lines of minimal code to do the same thing as the massive dependency WebEngine currently has.

We will soon be refactoring the Translator into its own classes of functionality, which will aim the project towards a stable release.
