  HISTORY:      02/29/2000   initial release
+               10/25/2001   (RD) Modified so that it recognizes a
+                           blank line
+               06/30/2003   (RD) replaced istrstream with istringstream
+                            to get rid of the annoying warning about
+                            using the strstream header
