"""This module provides everything needed to create a plugin.

resource - Get/set application wide resources

Classes to construct Actions:
    Action
    CheckAction (Checkbutton Action)
    RadioAction (RadioButton Action, should set the group attribute)
    ObjectAction (this is not an action, but it contains some code to make
                  instances of Actions behave like Action classes)

Each action is initialized. The window containing the action can be accessed
by the 'window' property.
