Remarks
The vdGroups class manages creation, lookup and lifecycle of vdGroup instances. Typically accessed via the Groups property, which is used to organize figures into logical groups for collective manipulation with vdSelection. It maintains fast lookup dictionaries by name and by id, supports document registration and serialization, and exposes collection operations.
