/*
For each page you require Multi-Add functionality, include this AddItems()
function beneath the other NebuCart includes, alternatively you can
copy and paste this entire function into NC_formatting.js or NebuCart.js

Build your pages as normal and make sure the input type for 
the prodID is a text box so the user can enter the amount required:
         <input type="text" name="prodID" value="">
At the bottom of the page make a call to the following function 
AddItems(), no parameter is required, instead we'll find all the 
products that have a quantity > 0 and we'll add them. If an item
already exists with the same options, it is not added.
<input type="button" onclick="Add()" value="Add my selections">
<a href="javascript:Add()" title="Add my selections">Add my selections</a>

This page is setup for use with the MultiAdd() function which works a
little differently to Add()
