TODAY'S GOAL:
* Neighbors needs a rewrite
* Neighbors algo isn't using greater parameter
* Clean up and document as much code as possible.
* Doxygen? Other docs tool?
* Add a method to render.cpp that sets terminal true color.
* limit as 1000 should be a constant

TODO:
* I can do headless windows in renderer for testing.
  - renderer.$window.setVisible(false);
* Think up an enemy system.
* Revisit map generation.
* Write a method for renderer that can translate coordinates.
* Can std::any be defaulted to a noop in the events?
* Save file isn't saving gold.
* Inventory needs to be better, but need some kinds of "weapons" or other loot to get and not just gold.
* Create a few more enemy types to fight.
* Devise a more complete map/world generator that can use the loot and enemies better.
* Maybe an LOS system, but the hearing version works pretty well so far.
* Probably a system for mapping collision types to sound effects, rather than having the GUI do it.

* Write a test that generates a ton of maps then confirms there's a path from one room to every other room?
* Lua integration

* check out SoLoud.

* BUG: When enemies die they can be overlapping another enemy.
