All the user to set the seed for the random number generator in cim.Identity.uuid(mRID, uri, name) by adding a fourth argument seed which can be a string or int. if mRID, uri, or name is defined it behaves exactly the same as it currently does regardless of whether seed was set or not. seed is only used when the other arguments are None.
