Generate tests for verifying complement relationships between problems.

Example

complement_test! {
    name: is_vc_complement,
    problem_a: IndependentSet<i32>,
    problem_b: VertexCovering<i32>,
    test_graphs: [
        (3, [(0, 1), (1, 2)]),
        (4, [(0, 1), (1, 2), (2, 3), (0, 3)]),
    ]
