* The parameter to this function can be a ResourceLoader module name or a function.
*
* If it's a module name, it will be loaded together with the VisualEditor core modules when
* VE is loaded. No special care is taken to ensure that the module runs after the VE
* classes are loaded, so if this is desired, the module should depend on
* ext.visualEditor.core .
*
* If it's a function, it will be invoked once the VisualEditor core modules and any
* plugin modules registered through this function have been loaded, but before the editor
* is intialized. The function can optionally return a jQuery.Promise . VisualEditor will
* only be initialized once all promises returned by plugin functions have been resolved.
*
* // Register ResourceLoader module
* mw.libs.ve.addPlugin( 'ext.gadget.foobar' );
*
* // Register a callback
* mw.libs.ve.addPlugin( function ( target ) {
* ve.dm.Foobar = .....
* } );
*
* // Register a callback that loads another script
* mw.libs.ve.addPlugin( function () {
