	like to move away in the long term. This is where we hope the components come into play, which
	you will encounter later.

	This is the most important class if you are going to hack on Unknown Horizons; it provides most of
	the important ingame variables.
	Here's a small list of commonly used attributes:

	* world - horizons.world instance of the currently running horizons. Stores players and islands,
		which store settlements, which store buildings, which have productions and collectors.
		Therefore, world deserves its name -- it contains the whole game state.
	* scheduler - horizons.scheduler instance. Used to execute timed events. Master of time in UH.
	* manager - horizons.manager instance. Used to execute commands (used to apply user interactions).
		There is a singleplayer and a multiplayer version. Our mp system works by the mp-manager not
		executing the commands directly, but sending them to all players, where they will be executed
		at the same tick.
	* view - horizons.view instance. Used to control the ingame camera.
	* ingame_gui - horizons.gui.ingame_gui instance. Used to control the ingame gui framework.
		(This is different from gui, which is the main menu and general session-independent gui)
	* cursor - horizons.gui.{navigation/cursor/selection/building}tool instance. Used to handle
			   mouse events.
	* selected_instances - Set that holds the currently selected instances (building, units).
