HelloWorld

This is a minimal Apache Causeway application, intended as a starting point to learn what the framework is all about.

Tip	For real-world development, we recommend you instead start with the SimpleApp starter app. It provides more structure and includes examples of fixtures, unit tests, integration tests, and BDD (Cucumber) specs.
