   The Routing Protocol for Low Power and Lossy Networks (RPL) uses
   objective functions to construct routes that optimize or constrain
   the routes it selects and uses.  This specification describes the
   Minimum Rank with Hysteresis Objective Function (MRHOF), an objective
   function that selects routes that minimize a metric, while using
   hysteresis to reduce churn in response to small metric changes.
   MRHOF works with metrics that are additive along a route, and the
   metric it uses is determined by the metrics RPL Destination
   Information Object (DIO) messages advertise.
