/**
 * GroundState contains all information that make individual runs of an application differ (such as execution date,
 * random seed, db-version, etc.).
 *
 * Upon creation, the GroundState gets a UUID, which is referenced by all graph. States can thus exist (be persisted,
 * remotely created and transmitted etc.) independent of the StateGraph and contain only the UUID of the GroundState and
 * thus the state relevant execution information.
