When the user drags and releases an Np or Ep over an element, there should be an "touchesEnded" method that checks to see what he released upon and, if that spot is an element, whether or not the released-upon element is of the appropriate type.

E.g. The user drags an Np draggable marker to an element. He releases on the element. That element is identified as the Np. He is correct; an Np marker is created behind that element.
