    What a committed IfcModel.author batch did.

    interface AuthoringResult {
        created: bigint[];
        ids: (bigint | undefined)[];
        removed: bigint[];
    }
    Index
    created: bigint[]
    ids: (bigint | undefined)[]

    Per operation, the id of the entity it produced; undefined for a removal.
