public interface DoubleList extends List<Double>, Comparable<List<? extends Double>>, DoubleCollection
List; provides some additional methods that use polymorphism to avoid (un)boxing.
Note that this type-specific interface extends Comparable: it is expected that implementing
classes perform a lexicographical comparison using the standard operator "less then" for primitive types,
and the usual compareTo() method for objects.
Additionally, this interface strengthens listIterator(),
listIterator(int) and subList(int,int).
Besides polymorphic methods, this interfaces specifies methods to copy into an array or remove contiguous sublists. Although the abstract implementation of this interface provides simple, one-by-one implementations of these methods, it is expected that concrete implementation override them with optimized versions.

It would not be normally necessary, but Iterable.iterator() is bizarrily re-specified
in List.

This differs from List.sort(java.util.Comparator) in that the results are
not assured to be stable, but may be a bit faster.
Unless a subclass specifies otherwise, the results of the method if the list is concurrently modified during the sort are unspecified.
