| # 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. :( |

Useful for when a blocking user experience is needed (in my case, didn't want people unwittingly loosing their place by scrolling while a modal required their attention): $.scrollLock() locks the body in place, preventing scroll until it is unlocked.
// Locks the page if it's currently unlocked
$.scrollLock();
// ...or vice versa
