The Poinsot Construction is the fundamental visualization of torque-free motion of rigid bodies. Per Goldstein: "the polehode rolls without slipping on the herpolhode lying in the invariable plane."
The methods included here allow for the exploration of torque-free, rigid body motion through the constructions of the kinetic energy and inertia ellipsoids (Binet construction and Poinsot construction).
Script binet_construction generates a (static) kinetic energy ellipsoid. Script poinsot_construction generates an animation of the Poinsot construction in the inertial and body-fixed frames.
See headers of individual files for more details on additional functionality.

As noted in previous discussion the original version of this code had multiple errors and the animation was not quite correct. The new code fixes these.

okay - guess mathworks doesn't like tar.gz. replacing with zip.
