/*
   Note: this module contains functionality for reading/writing 
         Euclid's binary io format, and opening and closing files.
         Additional io can be found in in mat_dh_private, which contains
         private functions for reading/writing various matrix and
         vector formats; functions in that module are called by
         public class methods of the Mat_dh and Vec_dh classes.
