Detailed Description

Records the re-fusion (deletion) of a virtual junction.

The constructor snapshots what a re-split needs: the upstream/ downstream conduit names, the length-ratio split position, the node invert and its map coordinate. undo() re-splits at the snapshot position and restores the invert and coordinate so a grade-break node comes back exactly.
