Added a link to the stable build

This algorithm is designed to find the distance of a certain region,
however it may have been better to do a quick check, rather than worrying
how many regions were loaded at once.

+The most recent stable windows build can be found [here](https://dl.dropboxusercontent.com/u/46669050/Tortuga.rar).
+
+Tortuga is an open source 2D multiplayer role playing game featuring permadeath (deletion of a character upon death). The emphasis of this game is on multiplayer cooperation, competition, exploration and customization. The game runs on customizable server software that can support up to 150 simultaneous players or more.
+
+This game is inspired by classic 2D RPGs, as well as more modern sandbox MMOs. This project is currently independently created and funded, with the goal of creating a game that will engage user's imagination and inspire a large modding community.

+	 * This algorithm is extremely complex and involed, but initial tests show
+	 * that it gives the right answers. The purpose is to determine how far off screen
+	 * a certain region is, so that it can be unloaded when necessary.
+	 * 
+	 * If the region is actually onscreen, then there's no reason to run the rest, so
+	 * the algorithm corrects for the camera's location, before checking the bounds of
+	 * the screen.
+	 * 
+	 * The next part is tricky. If X or Y is negative, then it is divided by the
+	 * graphical size of the regions, resulting in a usable integer, representing how
+	 * far from the screen it is in "region units". If, however, X or Y is larger than
+	 * 0, than first, the size of the screen is subtracted from that variable, before
+	 * it is then divided by the graphical size of a region. Finally, to compensate for
+	 * the off by one error, 1 is added at the end.
+	 *
+	 * Since only the magnitude of the distance in either direction is needed, this
+	 * method returns the largest absolute value of X or Y.
+	 * 
+	 * The final result of this algorithm is an integer representing how far, rounded
+	 * up, a certain region is from the screen's edges in any direction, measured in
+	 * "region units". This algorithm may be flawed, in which case, I recommend simply
+	 * replacing it with a boolean check, to see if the region's distance from the player
+	 * is larger than a certain value. This algorithm lacks the advantages I initially
+	 * expected, so that may be beneficial at some point.
