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