var compileTemplates = function() {
  _.each(App.Views, function(View) {
    if (View.prototype.templateId) {
      // The templateId references the id of a DOM element containing
      // the content of the template
      var html = jQuery('#' + View.prototype.templateId).html() || '';
      View.prototype.template = _.template(html);
    }
