Angle Calculation between Vectors Incorrect
The calculation for the angle between two vectors (e.g. https://git.rwth-aachen.de/monticore/EmbeddedMontiArc/simulators/commons/-/blob/master/src/main/java/de/rwth/montisim/commons/utils/Vec3.java#L89) is implemented incorrectly.
See this and OpenJFX Point3D Implementation for references.
