A bridge to integrate octave (gnu octave, a matlab clone) into java code.

This github project stems from https://github.com/AngeAnalytics/java-octave and shall be synchronized with it. The new site is http://www.simuline.eu/JavaOctave/.

rerequisites:

• java 8 is needed, we tested with java 11
• essentially all octave versions work (we don't know about prior 3.0.0) but we tested with 5.2.0
• currently, octave shall have package quaternion version 2.4.0 installed.
