// Revision 1.1  2000/06/19 19:59:33  eugenio
// Initial revision
//
// Revision 1.5  1998/11/20 23:48:07  mkl
// switch Boolean to MCFBool to avoid clashes with other typedef-ed bool types
//
// Revision 1.4  1998/11/20  05:32:17  mkl
// more verbose findFirstMedium with nicer return type; update index after volume exit
//
// Revision 1.3  1998/11/03  17:43:38  mkl
// changes to compile under egcs
//
// Revision 1.2  1997/11/12  07:49:12  mkl
// major bug fixes (mostly reverse_iterator specific) -- now good agreement with fortran tracing found number of tracks
//
// Revision 1.1  1997/11/11  01:17:47  mkl
// Major rewrite: simplify tracing loops; add x-, y-tracing loops
//
//
