title: Determining the size of a merged area
body: <p>Right, before we get off about merged cells, I hate them too, but I've to deal with them anyway. I cannot change anything about that now or in the future. As much as I would like to ;)</p>
  
  <p>Say I have some merged cells, I need to determine the amount of cells it spans.
  Say A1:A4 are merged, then I need to have the number of merged cells, 4, returned.
  Is  there any way to accomplish this?</p>
