// This binary allows us to replay the superstructure code over existing
// logfile. When you run this code, it generates a new logfile with the data all
// replayed, so that it can then be run through the plotting tool or analyzed
// in some other way. The original superstructure status data will be on the
// /original/superstructure channel.
