+//! The position indicator shows the mouse position on the map
+//!
+//! The exact position the mouse is currently on is shown unless hidden by the user (TODO). This
+//! helps to place things exactly where they should be on the map and let the user know where they
+//! are looking and where relative to them other things should be easily at all times. Currently, this
+//! is a simple HUD so it doesn't interact with anything in the world, but that may change in the
+//! future.
