A maze generator using a randomized Prim's algorithm

This is a plugin for the sbj42/maze-generator package.

Prim's algorithm is a method of generating a "minimum spanning tree" of an arbitrary graph. This adapts naturally to generating mazes, since every perfect maze is also a spanning tree. The walls in the maze are given equal weight, so we replace the part of Prim's algorithm that finds the minimum-weight edge with code that simply chooses a random edge.

Basically, this algorithm works by digging multiple random passages at a time, randomly deciding which passage to work on at each step. Compared to the 'recursive-backtracking' algorithm, this generator tends to have more, shorter dead ends.
