"""This is the main file which runs the Impossible Grid game. It imports the
local Grid class from grid.py, exceptions from igexceptions.py and sets the
width and height of the grid to 4.
If this file is not being imported (e.g. by PyDoc), the players are then
greeted and player 1 is asked for a number between 1 and the area of the grid.
The screen is then cleared for player 2, who has to cover player 1's number on
the grid; they are given prompts asking which rows and columns they would like
to cover until one number is left on the grid.
Player 1 wins if their number is left uncovered, otherwise player 2 wins.
