/**
 *  Antz_IntelliForm has 3 main purposes: 
 *    * Make hack attempts more cumbersome by seeding forms
 *    * Prevent the form from being re-submitted when you hit the back button
 *    * Save form data for when the page is re-visited
 *     
 *  The length of time that the form data is saved for is configurable in Antz_
 *      IntelliForm::expireTime
 *  Each page can save a form with a unique key name, so you can save many forms in 
 *      any one session
 *  You can delete a saved form using Antz_IntelliForm::clear(), this is good after 
 *      the form has been processed and the data does not need to be retained
 *  You can check if the form has been submitted by using Antz_IntelliForm::submitted() 
 *      ( returns boolean )
