/***********************************************************************
*
* getMiniCart		-	fetches cart content summary
*
* Returns:		-	HTML string for summary display
*
* Graham Bradley 2007
* Comments & bug reports to web@gbradley.co.uk
*
* To make editing the output HTML easier, output code has been split into
* nine 'template' strings.
*
*	tableOpen	-	the opening table code
*	itemLine	-	repeated for each item in the cart
*	shippingLine	-	for displaying shipping charges (if any)
*	vatLine		-	for displaying VAT on items & shipping (if any)
*	discountLine	-	for displaying discount total (if any)
*	surchargeLine	-	for displaying surcharge total (if any)
*	totalLine	-	for displaying the cart total
*	tableClose	-	the closing table code
*	emptyLine	-	displayed when cart is empty
*
* Within these templates, you can use variables to insert values into
* the summary, similar to variables in Actinic:
*
*	VAR:QUANTITY	-	The quantity of item in cart
*	VAR:TITLE	-	Abbreviated name of item
*	VAR:LINK	-	URL of item via the cgi-bin
*	VAR:PRICE	-	Formatted price of item
*	VAR:SHIPPING	-	Total of shipping applied
*	VAR:VAT		-	Total VAT on cart items & shipping
*	VAR:DISCOUNT	-	Total of discounts applied
*	VAR:SURCHARGE	-	Total of surcharges applied
*	VAR:TOTAL	-	Grand total
*
* Variables can only be used in the templates in which they are found.
