Define a function, nearest$\_$edge$\_$square$($x$,$ y$,$ length$),$ which returns a tuple containing an integer

$(0,1,2$ or $3)$ indicating which is the nearest edge and a float for the distance to the edge. The parameters

x$,$ y and length are all floats. x and y are the coordinates for the point in the square, and length is

the length of square. Assume the square has a lower left corner at $(0,0).$Use integers to represent the edges of the square.
