Find GIT_REPO/examples for some sample cubes. Briefly "aggregation group" is a way to build partial cubes.
By default, a 4-dimension full cube (A, B, C, D) will generates 16 cuboids, the combination of all 4 dimensions. But you can specify smaller aggregation groups, like (A, B), (C, D), to only generate the combinations between (A, B) plus the combinations between (C, D), which result 8 cuboids.
