Add Randomization of the deck

[Stevec4]

I know this is an old project, but I found it useful and wanted to share a small snippet of code to randomize the deck.
add this to the flash-cards.min.js and your deck will have a randomized list of questions.

 $('ul').each(function(){
            // get current ul
            var $ul = $(this);
            // get array of list items in current ul
            var $liArr = $ul.children('li');
            // sort array of list items in current ul randomly
            $liArr.sort(function(a,b){
                  // Get a random number between 0 and 10
                  var temp = parseInt( Math.random()* 5 );
                  // Get 1 or 0, whether temp is odd or even
                  var isOddOrEven = temp%2;
                  // Get +1 or -1, whether temp greater or smaller than 5
                  var isPosOrNeg = temp > 5 ? 1 : -1;
                  // Return -1, 0, or +1
                  return( isOddOrEven*isPosOrNeg );
            })
            // append list items to ul
           .appendTo($ul);  
			//console.log( ul );
      });
