+/** 
+Represents a UI window.
+
+Each window has a list of players that are currently using it
+When there's no player using a window, it is destroyed.
+A window consists of several areas of slots with similar functionality - for example the crafting grid area, or 
+the inventory area. Each area knows what its slots are (GetSlot() function) and can handle mouse clicks.
+The window acts only as a top-level container for those areas, redirecting the click events to the correct areas.
