The io.github.jpenren:thymeleaf-spring-data-dialect dependency was out of sync with thymeleaf causing an error when you tried to access the index page.
Additionally Added a TestApplication and revamped the TestContainers usage.
Collapsed domain model into a single class. Merged application configuration classes into a canonical Application class.
Tweaked UserInitializer to expose dedicated methods to make sure the parameter is only exposed if remote users are used.
Removed JavaScript based frontend as it was basically testing the Spring Data REST exposed API but not the data obtained through the Spring MVC controller. We're going to create a dedicated example for the Spring Data REST integration.
