* time in seconds to animate the action. For this example, atoms in model 2
* are moved towards atoms in model 1.

* The two atomspecs should each be for one model only, but may have more than
* one chain. The number of atoms specified should be the same for both
* models, though if not, Jmol may make a 'best effort' at superposition.
