/*
For each page you require Multi-Add functionality, include this 
script 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="AddItems()" value="Add my selections">
<a href="javascript:AddItem()" title="Add my selections">Add my selections</a>
*/
