/**
* The subclasses of this class provide actions to perform upon {@link Ext.form.Basic Form}s.
*
* Instances of this class are only created by a {@link Ext.form.Basic Form} when the Form needs to perform an action
* such as submit or load. The Configuration options listed for this class are set through the Form's action methods:
* {@link Ext.form.Basic#submit submit}, {@link Ext.form.Basic#load load} and {@link Ext.form.Basic#doAction doAction}
*
* The instance of Action which performed the action is passed to the success and failure callbacks of the Form's action
* methods ({@link Ext.form.Basic#submit submit}, {@link Ext.form.Basic#load load} and
* {@link Ext.form.Basic#doAction doAction}), and to the {@link Ext.form.Basic#actioncomplete actioncomplete} and
* {@link Ext.form.Basic#actionfailed actionfailed} event handlers.
