Commit JT 032219 

- fixed bug 1: precession_spin had no min_setup
- fixed bug 2: incorrect init of spins in neb/spin
- improved doc min_spin.txt (added eqs, and connected to related
files).

[Description:]



Impose a force torque to each magnetic spin in the group.

This fix applies a precession torque to each magnetic spin in the group.



Style {zeeman} is used for the simulation of the interaction

between the magnetic spins in the defined group and an external
