Maze generation system for godot-mapper plugin

This maze generation system automates the assembly of modular rooms.
The rooms are joined together via a minimal func_connector brush entity.
Self-intersections are prevented by performing AABB checks of map brushes.

Explanation of the system

func_connector entity is a simple box with the angle of entrance.
The build system will automatically find boxes with unique sizes to join.
Joinable rooms for each connector are provided by adding next property.
Here's a value example - { "rooms/01-aleph": 50%, "rooms/00-BREAK": 50% }.
Other room entities can specify maze_ignore property to disable AABB checks.

Maze generator supports the following options.

• maze_seed is a unique layout of the maze.
• maze_max_depth for how deep the maze can reach.
• maze_exit_depth for the exit rooms to at least be reached.
• maze_exit_count is the desirable number of exit rooms.
• maze_unpack will unpack rooms as unique nodes.

Unpacking is designed for isolated arenas locked by doors.

Global maze configuration is defined in func_connector+.gd script.
Uppercased naming convention is used for the maps that seal exits.

How to create interesting rooms

Getting procedural generation right is very difficult without a direction.
22 example rooms are based on the letters of Phoenician/Hebrew alphabet.
Languages provide memorable shapes for the rooms as well as how they naturally join.
Moreover, the letters can be further classified to give a special meaning to each room.
There are 3 mother letters, 7 doubles and 12 simples according to Sefer Yetzirah.
