Release and Explanation of generator

So, you downloaded the procedural facility. Lets say your a nerd like me, and you wanna know how it works.

Basically theres a startroom, end room, and corridors and rooms.

Basically it goes in 4 stages:

1: Generate start room. generates start room at spawn.

2: Generate Corridors. Generates corridors. Basically each room has doors, and it chooses a random door on the room, and gets a random door that already exists, and puts them together. 

3: generate rooms. generates rooms on the doors that already exist. Rooms cannot have corridors coming off them, and act like a dead end.

4: Generate End Room. Generates end room. 

Yeah thats how it works
