  Contents: routines for loading Bayes classifiers and data
            (common to the X11 and the Windows program)
  Author  : Christian Borgelt
  History : 18.02.2000 file created from file xbcview.c
            30.11.2000 cluster sets replaced by a full Bayes classifier
            13.05.2001 definition of E_ATTYPE removed
            12.04.2003 clustering result loading added
            15.05.2004 function bc_bvnorm added
            17.08.2004 radial basis function networks added
