Generating mazes

While Reeborg's World was primarily designed for beginners, it can be used to illustrate relatively advanced topics in a fun way.  For example, one can generate mazes using a depth-first algorithm.

Of course, generating mazes is only half the fun: the real fun is to use them to set Reeborg on a treasure hunt:

Fairly large mazes can be generated, but it does take a fair bit of time. I'm using many generic functions written for the world editor to change the world configuration; these are well-tested and designed for fool-proof interactive use, adding or removing one element at a time.  A more efficient way would be to manipulate directly the world object (implemented as a mixture of dict and lists - to use the Python terms, although they are in this case the javascript equivalents).
