SEEN and VISITED do the same thing.
This change moves the SEEN flag into epoch.h, then replaces uses of VISITED with SEEN and removes the definition of the VISITED flag.
The merge-order code needs to clear the SEEN flag set by the argument parsing to ensure correct operation. So it clears that one and, for completeness, BOUNDARY and DISCONTINUITY too.
