StableRevisionComparator implements a revision comparator, which is only based on stable information available in the two revisions presented to this comparator. This is different from {@link Revision.RevisionComparator}, which also takes the time into account when a foreign revision (from another cluster nodes) was first seen. This class is used in sorted collections where revision keys must have a stable ordering independent from the time when a revision was seen.

Revisions are first ordered by timestamp, then counter and finally cluster node id.
