These three methods, namely {@link thenBy}, {@link thenByDescending} and {@link thenByDir}, enable you to specify additional sort criteria to sort a sequence. These methods also return an OrderedEnumerable, which means any number of consecutive calls to thenBy, thenByDescending or thenByDir can be made.
      * <p>Because OrderedEnumerable inherits from {@link Enumerable}, you can call {@link Enumerable::orderBy orderBy}, {@link Enumerable::orderByDescending orderByDescending} or {@link Enumerable::orderByDir orderByDir} on the results of a call to orderBy, orderByDescending, orderByDir, thenBy, thenByDescending or thenByDir. Doing this introduces a new primary ordering that ignores the previously established ordering.
