/**
* Page Object pattern wraps an UI component with an application specific API allowing you to
* manipulate the UI elements without having to dig around with the underlying UI technology used. This is
* especially useful for testing as it means your tests will be less brittle. Your tests can concentrate on
* the actual test cases where as the manipulation of the UI can be left to the internals of the page object
* itself.
*
* <p>
* Due to this reason, it has become very popular within the test automation community.
* In particular, it is very common in that the page object is used to represent the html pages of a
* web application that is under test. This web application is referred to as AUT (Application Under Test).
* A web browser automation tool/framework like Selenium for instance, is then used to drive the automating
* of the browser navigation and user actions journeys through this web application. Your test class would
* therefore only be responsible for particular test cases and page object would be used by the test class
* for UI manipulation required for the tests.
*
* <p>
* In this implementation rather than using Selenium, the HtmlUnit library is used as a replacement to
* represent the specific html elements and to drive the browser. The purpose of this example is just to
* provide a simple version that showcase the intentions of this pattern and how this pattern is used
* in order to understand it.

* Application entry point

* <p>
* The application under development is a web application. Normally you would probably have a
* backend that is probably implemented in an object-oriented language (e.g. Java) that serves
* the frontend which comprises of a series of HTML, CSS, JS etc...
*
* <p>
* For illustrations purposes only, a very simple static html app is used here. This main method
* just fires up this simple web app in a default browser.
