func CartesianProduct

func CartesianProduct(setSizes []int) (<-chan []int, error)

CartesianProduct returns a channel that lists all the combinations of elements from the given setSizes to produce the Cartesian Product of all the values in the sets.

For example:

CartesianProduct([]int{3, 2})

Will produce the following int slices:

{2, 1},
{1, 1},
{0, 1},
{2, 0},
{1, 0},
{0, 0},

Each setSize must be greater than one.
