Clean-up on aisle code

It's more succinct than it was, but this code is still a nightmare to read and update. Let's try to refactor it a little more.

There's a lot of GetComponent.<Square>().player happening throughout the line. What if we made one function that would do that job, just to shorten up our code and make it a little more readable?

By setting up a function that accepts x and y as arguments, and spits out the value of a square's player variable, we'll have a handy and reusable piece of code for all kinds of situations. You should start writing the code into your project again.

function GetPlayer(x:int, y:int):int
{
  return aGrid[x,y].GetComponent.<Square>().player;
}
