- * Most non-trivial plugins will require extra modules to do their work. Typically
- * these include data classes, action classes, widget classes, or external libraries.
- *
- * This method receives a class name and loads the PHP file related to that class. By
- * tradition, action classes typically have files named for the action, all lower-case.
- * Data classes are in files with the data class name, initial letter capitalized.
- *
- * Note that this method will be called for *all* overloaded classes, not just ones
- * in this plugin! So, make sure to return true by default to let other plugins, and
- * the core code, get a chance.
