+Networked Battleship Implementation
+Jacob Feddersen
+
+Compile: `make`
+Run:     `./battleship`
+There are no command line parameters for this program
+
+I abstracted the network code for this game to the point where either a
+client or server is instantiated, and otherwise the rest of the code is
+exactly the same.
+
+The server prints all of the interfaces it knows so the user can select to
+which it should bind. It then prints the IP so the user can connect a client
+to it. The client prompts the user to enter an IP so it can connect.
+
+Controls:
+ * Move targeting pointer: Arrow keys
+ * Select target: Space
+
+Known bugs:
+ * Ncurses queues input while waiting for the opponent to move
+ * The game does not know how to handle when the opponent disconnects, and
+   either exhibits undefined behaviour or crashes
