Resolve #7

[nutjob4life]

📜 Summary

Merge this if you dare and resolve #7, which includes:

• Template docs that can be expanded upon so you get a default site
• Template "Hello World" app that uses resources in a jar so you get to exercise jar construction with non-compiled files
• Javadocs to populate the site reports including the package-level docs that everyone forgets
• Template unit test that can be modified and expanded upon
• (The gh-pages branch was already there; see As a developer, I want to have java template repo #7)
• Site look-and-feel like other PDS repositories
• Stabel CI/CD workflow
• Updated documentation throughout
• A contributor's guide
• A code of conduct
