// One solution might be to have an AJAX spinner in a standard location that gets shown when AJAX requests start and hidden when AJAX requests complete. To do this globally in jQuery:
// http://robots.thoughtbot.com/automatically-wait-for-ajax-with-capybara

jQuery.ajaxSetup({
  beforeSend: function(xhr) {
    $('#spinner').show();
  },
  // runs after AJAX requests complete, successfully or not
  complete: function(xhr, status){
    $('#spinner').hide();

// Slick little method to create a bitmask from an array of boolean values. (for Javascript)
function bitMask(a, b) {
    var m = 0, i;
    
    if (b !== undefined) { a = Array.prototype.slice.apply(arguments); }
    
    for (i = 0; i < a.length; i += 1) {
	if (a[i] !== false) { m += Math.pow(2, i) };
    }
