Selection of an item triggers the reading of all the display
data for that particular model:
ribbons, atoms, bonds, polygons, dots, text, styles, coloring, orientation
(See Data Preparation)
If you subsequently edit any data file, use the Menubar File ReRead Data option to update the display.
Each *.model file in the directory from which you run ribbons generates an entry in the model submenu. Each string displayed on the menu is taken from your *.model file.
The menu presented above is seen when you run `ribbons-demo'.
All the files are found in the $RIBBONS_HOME/data directory.
