Develop Java version of Kotlin code

[nextcen-dgemoets]

To facilitate AIF maintenance (e.g., supporting the ontology developed by the Ontology working group), develop a Java version of the current Kotlin classes. It adds another language into the entire collection of languages that we have to support. Kotlin classes can still be used in cases where no further maintenance is planned (e.g., Seedling ontology, ColdStart).

See Next Century's Jira Issue AIDA-447.

The Java version of AIF has been developed. The Kotlin classes still exist in the jarfile for the moment, although the file was renamed to aida-interchange-1.0-SNAPSHOT.jar. Kotlin users can still use the edu.isi package, but will need to update their jarfile name.
