Require 80% Code Coverage as Measured by JaCoCo for New Contributions

[ryans58]

Maintainers & contributors will enforce a minimum of 80% code coverage within any new contributions to the Fluxnova platform. Code coverage will be measured by JaCoCo (https://github.com/jacoco/jacoco, licensed under EPL 2.0), and both instructions coverage and branches coverage will need to be >= 80%.

Instructions to developers:

1. As a requirement, JaCoCo unit test coverage analysis needs to be performed on all newly-contributed code, and the results need to be provided in all pull requests.
2. Both the branches and instructions coverage levels should be >= 80%. See the example below for the HTML output produced by JaCoCo.

Contributors won't need to use SonarQube for instrumentation of test results.
