    MoinMoin - ManageUsers Macro

    Based on functions taken from:
        userform.py
        MoinMoin - UserPreferences Form and User Browser
        @copyright: 2001-2004 by Jürgen Hermann <jh@web.de>

    To use this macro the following procedure (potentially UNSAFE as it makes a link to user file public)
    should be inserted into user.py (somewhere near the def save()):

    def getFilename(self):
        return self.__filename()

    When an account is deleted from Wiki, it's necessary to clean the cache.
    This macro only cleans user cache in current Wiki,
    so if there's a farm, you'll have to clean cache in other Wikies on your own or using another macro.
