Zero out the z-dimension velocity and force on each atom in the group.

This is useful when running a 2d simulation to insure that atoms do
|
|
not move from their initial z coordinate.
|

The forces due to this fix are also imposed during an energy
|
|
minimization, invoked by the "minimize"_minimize.html command.
