/**
* CoffeeCup Flash Form Builder: Form Results Handler
*
* This file is in charge of handling the form results
* posted from the CoffeeCup Flash Form Builder SWF.
* It has several primary functions:
*
* - Assure that the user is running the proper version of
* PHP and has properly configured their server for
* CoffeeCup Flash Form Builder by uploading the provided
* files and assigning the appropriate server settings
* and permissions.
* - Upload a file if the '$_FILES['Filedata']' variable is
* populated
* - If the '$_POST' superglobal array has been populated,
* process the form by:
* - Reading the config file provided in the '$_POST['xmlfile']'
* variable.
* - Saving the form data to a file if the 'CC_FB_SAVE_FILE' constant
* has been populated.
* - Saving the form data to the database provided in 'CC_FB_DB_ADDRESS'
* if the 'CC_FB_DB_ADDRESS' constant is populated.
* - Emailing the form data to the form owner via the address provided
* in the '$_POST['_ALT_EMAIL']' variable or the '$_POST['mailto']'
* variable if the '$_POST['_ALT_EMAIL']' variable is not populated.
* - Emailing the form data to the form user via the address provided in
* the '$_POST['eM']' variable if the '$_POST['eM']' variable has been
* populated and the 'emailuser' config option is set to 'true'.
* - Taking the form user to the landing page provided in the
* '$_POST['thankyoupage']' variable or to a default landing page
* if the '$_POST['thankyoupage']' is empty.
* - Prints out an informational page with version numbers and release
* dates if an error occurs or if this script is called without
* the '$_POST' superglobal or the '$_FILES['Filedata']' variables
* being set.
