I'm going to change the tuple3 class; i am writing test cases to ensure
i don't break things when i do
larger maze test

created a method to more easily construct mazes by hand
another simple test, address simple warning

addressing more ide warnings

kruskal maze tests

static import the directions to be more concise
another complex test

since this has a differenct constructor, then i may as well test to make
sure it works
added tests for prim
