PrettyBox

class PrettyBox

Fixed-layout text table redrawn in place on the terminal.

Used for the live progress display during event generation (Verbosity::pretty). print_first draws the initial box; print_update moves the cursor back up and repaints the same lines, so the box appears to update rather than scroll.
