/***********************************************************************
*
* 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.
