Detailed Description

this file allow some transformation when retrieving values from untrusted values

basically, wuth magic quotes, php can escape automatically or not values. as I find it painfull to browse automatically all variables and strip or unstrip them, I prefer to force developers to call this method to always retrieve stripped variables. It is then up to the developer to properly escape untrusted variables
