Detailed Description

Base class for editor actions.

An action is constructed in response to a user command, then executed on the map. An undo action is returned by default via pointer, caller-owned). It is possible to call an action without creating the undo action. Actions report failure via exceptions. Code that only deals with actions polymorphically should only need to include this header file.
