// this is largely a re-worked version of Options.js, but is designed specifically for Collection pages (basically department pages showing multiple products
// where you can buy multiple products with the same add-to-basket - so we need to show separate option dropdowns for each product. - tricky.																										 

// mind dump of what needs to happen:

/*

	All the colour/size/option divs that hold the selects will be prefixed with the sku.
	All the option data itself will be held in an associative array, keyed by the sku.
	
	we then need to loop over the option data array and update each option div with the required select list etc.


optiondata needs these keys building by the template. template will need to add to this structure as it templates each product:

OptionsData =  new Array();
OptionsData[0] = new Object();
OptionsData[0]["price"] = 70.0000;
OptionsData[0]["colour"] = "No Colour";
OptionsData[0]["l_colour_img"] = "0";
OptionsData[0]["specialprice"] = "0";
OptionsData[0]["description"] = "2284818905223";
OptionsData[0]["s_colour_img"] = "0";
OptionsData[0]["cost"] = 70.0000;
OptionsData[0]["size"] = "One Size";
OptionsData[0]["vatrate"] = 17.5000;
OptionsData[0]["stocklevel"] = 9999;


============================================
Assumes the following has been built in the product rendering template in javascript:

// --- following in department page template, above the products ----
OptionsData = new Array();

// --- /end ---------------------------------------------------------

// --- following in the product rendering template ------------------
OptionsData["%pub.product.skuEscaped%"] = new Array();
currentProductOptionCount = 0;
%pub.loopover|pub.product.complexOptions|products/complexOptionJSOutput|complexOption%

----- following in the looping option template "complexOptionJSOutput" ------

%complexOptionstart%
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount] = new Object();
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].price = %pub.product.complexOptions.price.valueFormatted%;
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].rrp = %pub.product.complexOptions.price.rrpFormatted%;
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].colour = '%pub.product.complexOptions.colour.description%';
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].size = '%pub.product.complexOptions.size.description%';
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].option = '%pub.product.complexOptions.option.description%';
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].largeColourSwatch = TO DO!;
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].smallColourSwatch = TO DO!;
OptionsData["%pub.product.complexOptions.parentSkuEscaped%"][currentProductOptionCount].vatRate = %pub.product.complexOptions.price.vat.rate%;
