  /**
  * 
  The "deleteData(offset,count)" method removes a range of
  characters from the node.  Delete data at the beginning
  of the character data.
  
  Retrieve the character data from the last child of the
  first employee.  The "deleteData(offset,count)"
  method is then called with offset=0 and count=16.
  The method should delete the characters from position
  0 thru position 16.  The new value of the character data
  should be "Dallas, Texas 98551".
