// Project Name:   The FPGA Othello Game

// Target Devices:
11 
// Tool versions:
12 
// Description:
13 
//              Will actually make a move in a given Othello board.
14 
//    Input: current board, (X,Y) - where to move, player
15 
//    Output: modified board
16 
//
17 
//    What do we have here, is a completly board mesh. 8x64 cells connected.
18 
//    64 cells for each direction (I-VIII). The result is combined from each
19 
//    direction output
20 
//    Hope this method takes much less area then having only 64 cells but with
21 
//    more complicated logic inside each cell. (4*8 inputs/outputs vs 4 inputs/outputs).
22 
//

// Dependencies:

//              move_cell

// Additional Comments:

//      Finally, combinational method....
