public class SimpleAssignmentStrategy.AnalysisContext.StrengthComparator
StrengthComparator is an Comparator that can be used to compare two Member objects based on their "distance" from a given set of members (as represented by an Ownership object). Member distances are expressed with the granularity of "machine", "rack", and "site".
A member is ordered "lower" than another member if it has a larger combined distance from the reference members (ownership) (i.e. it is "stronger"). Members with equivalent distances are ordered arbitrarily.
Note: This comparator does not define an ordering that is "consistent with equals". If used in a context requiring such a natural ordering, it should be chained with comparator that does provide a natural ordering.
