/** Action - An action.
* Action represents a single named action.
*
* The main interface to an action is that it can be activated with activate().
* This results in the signal_activate() signal being emitted. An activation
* has a Glib::VariantBase parameter (which may be <tt>0</tt>). The correct
* type for the parameter is determined by a static parameter type (which is
* given at construction time).
*
* An action may optionally have a state, in which case the state may be set
* with change_state(). This call takes a Glib::VariantBase. The correct type
* for the state is determined by a static state type (which is given at
* construction time).
*
* The state may have a hint associated with it, specifying its valid range.
*
* Action is merely the interface to the concept of an action, as described
* above. Various implementations of actions exist, including SimpleAction and
* Gtk::Action.
*
* In all cases, the implementing class is responsible for storing the name of
* the action, the parameter type, the enabled state, the optional state type
* and the state and emitting the appropriate signals when these change. The
* implementor responsible for filtering calls to activate() and change_state()
* for type safety and for the state being enabled.
*
* Probably the only useful thing to do with a Action is to put it inside of a
* SimpleActionGroup.
