Create all passed in landmarks along with a set of groups in one go.

Create all passed in landmarks along with a set of groups in one go.

The format for the passed in landmarks is expected to be [name, x1, y1, z1, x2, y2, z2], representing a shared landmark at locations (x1, y1, z1) for group A and (x2, y2, z2) for group B.

The format for the optionally passed in links is: [group_name_1, relation_name, group_name_2] elements, representing a relation between two groups. Whether group A and B map to 1 and 2 or vice versa depends on the semantics of the relation.
