# --------------------------------------------------------------------
# An implementation of Kruskal's algorithm for generating mazes.
# Fairly expensive, memory-wise, as it requires memory proportional
# to the size of the entire maze, and it's not the fastest of the
# algorithms (what with all the set and edge management is has to
# do). Also, the mazes it generates tend to have a lot of very short
# dead-ends, giving the maze a kind of "spiky" look.
# --------------------------------------------------------------------
# NOTE: the display routine used in this script requires a terminal
# that supports ANSI escape sequences. Windows users, sorry. :(
