	////////// USAGE NOTES \\\\\\\\\\\\
	
	PARAMETERS
	$loginid 		: Your Authorize.net Login ID
	$trankey 		: Your Authorize.net Transaction Key
	$ccnum 			: The system removes any spaces in the string to meet Authorize.net requirements
	$ccexpmonth 	: 2 digit month string
	$ccexpyear 		: 2 or 4 digit year string
	$ccver 			: The 3 or 4 digit card verificaton code found on the back of Visa/Mastercard and the front of AmEx
	$live 			: Whether to process as a live or test transaction - true : Live Transcation - false : Test Transaction
	$amount			: Total amount of the transaction. This must include both tax and shipping if applicable.
	$tax			: Tax amount charged (if any)
	$shipping		: Shipping cost (if any)
	$desc			: Description of the transaction to be logged into Authorize.net system
	$billinginfo	: Associative Array containing values for customer billing details
	$email			: Customer email
	$phone			: Customer phone
	$billinginfo	: Associative Array containing values for customer shipping details
	
	RESPONSE
	$response : Array (1 based) containing the Payment Gateway Resonse fields 
	
	// Important Response Values
	$response[1] = Response Code (1 = Approved, 2 = Declined, 3 = Error, 4 = Held for Review)
	$response[2] = Response Subcode (Code used for Internal Transaction Details)
	$response[3] = Response Reason Code (Code detailing response code)
	$response[4] = Response Reason Text (Text detailing response code and response reason code)
	$response[5] = Authorization Code (Authorization or approval code - 6 characters)
	$response[6] = AVS Response (Address Verification Service response code - A, B, E, G, N, P, R, S, U, W, X, Y, Z)
					(A, P, W, X, Y, Z are default AVS confirmation settings - Use your Authorize.net Merchant Interface to change these settings)
					(B, E, G, N, R, S, U are default AVS rejection settings - Use your Authorize.net Merchant Interface to change these settings)
	$response[7] = Transaction ID (Gateway assigned id number for the transaction)
	$response[38] = MD5 Hash (Gateway generated MD5 has used to authenticate transaction response)
	$response[39] = Card Code Response (CCV Card Code Verification response code - M = Match, N = No Match, P = No Processed, S = Should have been present, U = Issuer unable to process request)
	
	For more information about the Authorize.net AIM response consult their
	AIM Implementation Guide at http://developer.authorize.net/guides/AIM/ and
	go to Section Four : Fields in the Payment Gateway Response for more details.
	
	NOTES
	This component is meant to abstract payment processing on a website. 
	As varying sites require different requirements for information, security,
	or card processing (like changing Address Verification requirement) the
	component does not try to provide any logic to determine if a transaction
	was successful. It is up to the user implementing this code to process the
	response array and provide response accordingly.
