/* * @name DVectorSlice output stream function.
  *
  * This is a functions that are used to output a DVectorSlice object
  * to a char based output stream.
  *
  * The output format is diferent depending on the on whether the
  * bits #LinAlgPackIO::ignore_dim_bit# and #LinAlgPackIO::no_insert_newlines_bit# are set.
  * If #exta_flags & LinAlgPackIO::ignore_dim_bit != 0#
  * then the output format is:
  *
  * Case 1\\
  * #v.size()#\\
  * # v(1)  v(2)  v(3) ... v(v.size())#\\
  *
  * If #exta_flags & LinAlgPackIO::ignore_dim_bit == 0# then the output format is:
  *
  * Case 2\\
  * # v(1)  v(2)  v(3) ... v(v.size())#\\
  *
  * Each of the elements are are put into columns according to the width set in the 
  * output stream #os# and other formating commands when it is called.  Even if the set
  * width is 0 or less than
  * the number of char's for the element a space ' ' will be inserted between them.
  * The elements are formated according to the format in the stream #os#.
  *
  * If #exta_flags & LinAlgPackIO::no_insert_newlines_bit == 0# then a newline charactor
  * will not be inserted after the last element, otherwise (by default) it will be.
  *
  * If #vs.size() == 0# then no elements will be output and if
  * #exta_flags & LinAlgPackIO::ignore_dim_bit == 0# then only the operation
  * #os << vs.size() << endl;# will be performed.
  *
  * If any of the output operations fails then a #std::ios_base::failure# exception is thrown.
