* Function
* takeScreenShot(fileName, extension)
* - Takes a screenshot of the game window with an extension of your
* choice. For example, jpg, jpeg, gif, png.
* Example: KR.takeScreenShot("MyFirstScreenShot", "png");
* - This sends a picture called MyFirstScreenShot.png to your screenshot folder,
* and creates one if it doesn't exist.
