solution(3,2)
// will return the following:
[
    [{x: 0, y:0}, {x:1, y: 0}],
    [{x: 0, y: 1}, {x:1, y: 1}],
    [{x: 0, y: 2}, {x:1, y: 2}],
]

solution(99,2)
// will return the following:
[
    [{x: 0, y:0}, {x:1, y: 0}],
    [{x: 0, y: 1}, {x:1, y: 1}],
    [{x: 0, y: 2}, {x:1, y: 2}],
    ...
    [{x: 0, y: 98}, {x:1, y: 98}],
