View Change 1.0
---------------

REQUIREMENTS: VMD Version 1.4 or newer 

DESCRIPTION:
        Provides four commands which can be used to save and restore
        VMD eye viewpoints, and smoothly interpolate between them.

PROCEDURES:
        save_viewpoint    - save current viewpoint
        restore_viewpoint - change  current viewpoint  to a saved one
        move_view         - smoothly move between saved viewpoints (see Warning)
        write_viewpoints  - write viewpoints to a disk file (read back in via 'source')

BUGS:
        Warning: this script does the math cheaply, i.e. only interpolates
        transformation matrices, many sorts of extreme viewpoint changes will 
        look odd to bizzare. This is often cured by segmenting a drastic 
        camera move into smaller ones
