connect-four

Build a connect-four game for the terminal, that supports two local players.

The game should support two players (X, O) until there is one winner. Connect four is a type of m-n-k game. An m,n,k-game is an abstract board game in which two players take turns in placing a stone of their color on an m-by-n board, the winner being the player who first gets k stones of their own color in a row, horizontally, vertically, or diagonally.
