Double the size of cell when print

[kbumsik]

Our maze currently prints only a single character size cells. But it restricts expression our algorithms.
So we need to increase the size. Here is how our sample maze should look like (it replaces a file simulation/1.txt

 __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ 
|  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  |
 ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** 
|  *  *  *  *  *  *  *  *  *  *  *  *  *  *  *  |
 ** ** ** ** ** ** ** __ ** ** ** ** ** ** ** ** 
|  *  *  *  *  *  *  |  |  *  *  *  *  *  *  *  |
 __ __ __ __ __ __ __ .. ** ** ** ** ** ** ** ** 
|  .  .  .  .  .  .  .  |  *  *  *  *  *  *  *  |

|  |  .  .  .  .  .  .  |  |  *  *  *  *  *  *  |
 .. .. __ __ __ __ __ __ .. ** ** ** ** ** ** **

|S |  .  .  .  .  .  .  .  .  .  |  *  *  *  *  |
 __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ 

And when print with distance:
