/**
 * 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 )
