Code base modernized

[sualeh]

All, thank you for your support for this project. Please be sure to put a star on the repo. I have updated and modernized the code-base, and tests run using JUnit 5. Builds are run automatically using GitHub Actions. I will start going over the source code again, and update the comments and code.
