Prevent Twitter Typeahead drop down overlap due to IE7 z-index behavior (position:relative on container causes typeahead inputs after it to be a higher z-index by default [causing the drop down to be shown under it], but this makes it so each typeahead container decreases in z-index as it's later in the page).

var zIndexNumber = $('.twitter-typeahead').length+1;
$('.twitter-typeahead').each(function() {
	$(this).css('z-index',zIndexNumber);
	zIndexNumber -= 1;
});
