00031    Note: this module contains functionality for reading/writing 
00032          Euclid's binary io format, and opening and closing files.
00033          Additional io can be found in in mat_dh_private, which contains
00034          private functions for reading/writing various matrix and
00035          vector formats; functions in that module are called by
00036          public class methods of the Mat_dh and Vec_dh classes.
