/**
* 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 )
