After this Court granted writ of error on two applications in this case, the parties informed the Court that they had settled the issues between them. In a joint motion they request that the judgment and opinion of the court of appeals and the judgment of the district court be vacated, and that this cause be dismissed as moot. The motion does not state whether the parties have agreed to the allocation of costs.
