Time for action – pseu pseu pseudocode

To translate our prioritized peudocode strategy list into actual code, I propose that we turn each attempt at playing a piece into its own function. If we find a valid move, the function will return the square where the computer should play a piece. If there's no valid move, the function will return null, which is the computer code equivalent of "does not exist/totally isn't a thing".

In the ComputerTakeATurn function, let's get rid of (or comment out) the code that randomly chooses a square, which is bolded in the following code:

function ComputerTakeATurn()
{
  var square:GameObject;
  
  var aEmptySquares:List.<GameObject> = new List.<GameObject>();
  
  for(var i:int = 0; i < aSquares.Length; i++)
  {
