Adding Initial UnitTests and Required Dependencies

[LeviMatus]

What does this feature do?

This feature adds Maven support for Junit5 and introduces a first series of unit tests for the Orianna abstract and sub classes.

Pom.xml

• Added maven-surefire plugin v 2.22.0 which is the first to include full support of JUnit5.

  tests/.../Orianna.java

• Added a starting test suite for Orianna. This tests the construction of the Configuration and Settings classes. It also tests that the mutator methods work as expected.

Motivation, context and linked issue

This is motivated by #75. I saw that there had been no work done on this, so I thought I'd add in a simple test suite so that anyone who wants to help out can just start writing tests and not worry about getting the configurations set up.

How has this been tested?

With unit tests!

You can execute the maven test task, or execute mvn test from your terminal.

Types of changes

• [ ] Bug fix (non-breaking change which fixes an issue)
• [x] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)

Outstanding Work

• Mock objects and responses in the rest of Orianna using a library like Mockito.
• Integrate with TravisCI (or other preferred CI framework).

Thanks for getting the process started on this, and sorry for taking so long to get around to merging it. We're back in action on development of Ori now, and hopefully this can help us get some much needed unit test contributions.

Thanks for the PR!
