Implementation of a reusable solver for ODEs describing motion in 3D.

***Describe the issue*** Create a 3d ODE solver as reusable script/prefab

Prof. Hadley has many scenarios on his [website](http://lampz.tugraz.at/~hadley/physikm/script/motion/odeFxyzp.en.php) which aren't yet available in the 3D Motion Simulation experiment

***Describe the issue*** Improve the rendering of trajectories, use Quantities to improve the UI, etc.
