About hello

Demo project showing executable Jar for "Hello, World" non-GUI app. This is the generated archetype POM with an extra description, a modified version (removed "-SNAPSHOT"), updated JUnit from version 3 to 4 (but it still auto-generates JUnit 3 style tests), uses Java 9, uses UTF-8 for text files, updated the site plugin to include the unit test report, and added source code cross-reference plugin to the reports. See https://maven.apache.org/pom.html for details on POM.xml settings.
