Social Media Buttons
All dependent libary files to make these buttons work are included once per page
as socialmedia.js. This template may be included multiple times per page
so long as the following exist in the pdict :

--Required--
SitePreference FacebookAppID
pdict.Product
</iscomment>
<isscript>
importScript("product/ProductImageSO.ds");
var FacebookAppID : String = dw.system.Site.getCurrent().getCustomPreferenceValue('FacebookAppID');

//PDP Url for current product
var shareURL : dw.web.URL = dw.web.URLUtils.http("Product-Show", "pid", pdict.Product.ID);
var encodedShareURL : String = dw.crypto.Encoding.toURI(shareURL.toString());

//PDP main image
var imageURL : dw.web.URL = new ProductImage('pdp', pdict.Product, 0).getURL();
var encodedImageURL : String = dw.crypto.Encoding.toURI(imageURL.toString());

//Text to display for Product Sharing
var productText : String = dw.crypto.Encoding.toURI(pdict.Product.name);
