public class NaturalOrderComparator
extends java.lang.Object
implements java.util.Comparator<java.lang.String>

comparator which takes two strings and puts them in an order with special rules for numbers to be placed in numeric order; e.g. "10">"9", including when those numbers occur in the midst of equal text; e.g. "a10" > "a9"; but not if the text differs; e.g. "a10" < "b9"

class is thread-safe. nulls not supported. (to support nulls, wrap in guava: Ordering.from(NaturalOrderComparator.INSTANCE).nullsFirst())
