Parameters

$branch: A treeNode object. Determines if the URL points to itself, or possibly one of it's children, if present.

If the URL points to itself or one of its products, it displays its name, and expands to show its children, otherwise displays a link and a count of the products in it. If the URL points to one of it's children, it still displays a link and product count, but must still be expanded. Otherwise, it is collapsed and a link.

Return value

An array whose first element is true if the treeNode is in hierarchy of the URL path. The second element is the HTML of the list item of itself and it's children.
