	This is the most important class if you are going to hack on Unknown Horizons; it provides most of

	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).
