/**
 * MultiFormTest
 * For testing purposes, we have some test classes:
 * 
 *  - MultiFormTest_Controller (simulation of a real Controller class)
 *  - MultiFormTest_Form (subclass of MultiForm)
 *  - MultiFormTest_StepOne (subclass of MultiFormStep)
 *  - MultiFormTest_StepTwo (subclass of MultiFormStep)
 *  - MultiFormTest_StepThree (subclass of MultiFormStep)
 *
 * The above classes are used to simulate real-world behaviour
 * of the multiform module - for example, MultiFormTest_Controller
 * is a simulation of a page where MultiFormTest_Form is a simple
 * multi-step contact form it belongs to.
