🪀 Spinning Top - 2D Precession Plane: Axis Tip Trace, Nutation and the Sleeping Top

2D companion of the Spinning Top: a heavy symmetric top integrated from the Euler equations, with a side view and a top view of the axis-tip trace showing precession and nutation, spin friction, live angle and rate graphs, and checks of energy conservation, steady precession and the slow-precession formula.
