EMBED SCROLL PROTECT

AUTHOR: Michael Bregnbak
DESCRIPTION: When embedding content sometimes scrolling when mouse is over embedded content will interact with content instead of scrolling page (e.g. zoom on Google Maps). 
The Embed Scroll Protect will protect against this by creating an invisible overlay. Clicking this overlay will remove it and allow users to interact with content.
HOW-TO-USE: $('.some-selector').mbEmbedScrollProtect();
Now you can put class some-selector on e.g. Google Maps iframe.

	        // add markup
	        this.wrap('<div class="embed-scroll-protect-wrapper"></div>');
	        this.before('<div class="embed-scroll-protect-overlay"></div>')

	        var $wrapper = $('.embed-scroll-protect-wrapper');

GENERATE UNIQUE ID

AUTHOR: Michael Bregnbak
DESCRIPTION: Generates a unique identifier (string). Optional parameters: prefix (string), addRandom (boolean). 
First creates a timestamp (ms since epoch). Optionally adds a set prefix and appends a random number between 1-1.000.000.
Not 100% guaranteed unique - but close enough for everyday use.

*************************************************************/

	function mbGenerateUniqueId (prefix, addRandom) {

		var prefix = (typeof prefix != 'undefined') ? prefix : "";
		var dateTimeStamp = new Date().getTime();
		var uniqueId = prefix + dateTimeStamp;

		if (typeof addRandom != 'undefined') {
			if (addRandom === true)	{ 
				var randomNumber = Math.floor(Math.random() * 1000000) + 1;
				uniqueId = uniqueId + "r" + randomNumber; 
			}
		}
		return uniqueId;
