New and improved algorithms

Fixed an error in the implementation of the Aldous-Broder algorithm that caused it to be biased towards shorter paths with dead ends.

Added another unbiased algorithm, Wilson's algorithm!

Nothing's changed

Nothing has changed in how the program is used, but the code is prettier. And it should run unnoticeably faster. That's useful, right?

Executables!
