mkSimpleRotatingLogger :: FilePath -> String -> Int -> SimpleRotatingLogger

mkSimpleRotatingLogger d prefix n creates a logger that will write to directory d. The log "rotates" (starts a new log file) every n records. Log files follow the naming convention prefix.k, where k is the number of the last log record contained in the file. If logging has already been set up in directory, then logging will continue where it left off; appending to the most recent log file.
