## Tabbed Editor Window Extension - provide tabs in IDLE's editor
##
## About:
##
## This extenion is a gross hack on the object system of IDLE.
## The first EditorWindow instance gets configured as a TabManager
## and subsequent EditorWindow instances use a duck-typed Frame instead
## of a toplevel Tk object.
##
## The tab bar itself works best under Linux. Under MacOSX, the buttons
## are misplaced. Under Windows, the scroll wheel doesn't move the tabs.
