Class for all schrodinger Tkinter widgets. Takes care of retrieving
defaults for different widget classes, setting proper behavior, etc.
The class has the capability to retrieve generic defaults, environment
specific defaults (environ is a possible widget argument,
"dialog," "normal," etc.), and packing or grid
defaults. The widget classes below provide examples of how to use the
schroWidget class.
