[Chimera-users] Script for positioning particles according the coordinates.

There are two scripts (placem.py and place.py) on the Chimera Python
scripts web page
that will place models at specified positions. With the placem.py
script you specify the models/maps to open and the x,y,z translations
and optionally the rotation as a quaternion, one model on each line.
You can repeat the same model. The place.py script places multiple
copies of a single model specifying translation and rotation using a 3
by 4 matrix.
