    public class StringSort
extends java.lang.Object
implements java.lang.Iterable<java.lang.String>, java.io.Closeable
    Utility class to store a list of string and perform sort on that. For small size the list would be maintained in memory. If the size crosses the required threshold then the sorting would be performed externally
