//       Class : LineStream
// Description : This is a special ostream that writes to a memory
//               buffer, like ostrstream.  However, its contents can
//               be continuously extracted as a sequence of lines of
//               text.
//
//               Unlike ostrstream, which can only be extracted from
//               once (and then the buffer freezes and it can no
//               longer be written to), the LineStream is not
//               otherwise affected when a line of text is extracted.
//               More text can still be written to it and continuously
//               extracted.
