// Initial revision
//
// Revision 1.5  1998/11/20 23:48:10  mkl
// switch Boolean to MCFBool to avoid clashes with other typedef-ed bool types
//
// Revision 1.4  1997/11/22  20:26:37  mkl
// keep track of fortran name of planes
//
// Revision 1.3  1997/11/11  01:17:49  mkl
// Major rewrite: simplify tracing loops; add x-, y-tracing loops
//
// Revision 1.2  1997/08/27  03:31:49  mkl
// moved 'contains( particle )' to 'contains( wtrack )' and added Volume::distanceToExit()
//
// Revision 1.1  1997/07/03  03:33:57  mkl
// new approach: surfaces vs volumes; box tracing
//
