16  * @file
17  * Editor action classes. Some important points:
18  * - This is a polymorphic hierarchy of classes, so actions are usually passed around
19  * as editor_action pointers
20  * - The pointers can, in general, be null. Always check for null before doing anything.
21  * The helper functions perform_ that take a pointer do that.
22  * - The perform() functions can throw when an error occurs. Use smart pointers if you
23  * need to ensure the pointer is deleted.
