  Performs an heuristic method to calculate div elements sizes in order to have a good aspect ratio.
  
  Parameters:
  
  tail - An array of nodes.
  initElem - An array of nodes, containing the initial node to be laid out.
  w - A fixed dimension where nodes will be laid out.
  coord - A coordinates object specifying width, height, left and top style properties.
