var myClass = function() {

   this.attribut1 = "Heisenberg";
   this.attribut2 = "Heisenberg";

   getAttribut1 : function() {
      return this.attribut1;
   }

}

var element = new myClass();

alert(element.getAttribut1()); // should output attribut1

// Appending something via prototype
element.prototype.newattribute = "This should be a new attribute";
