* A List of double's; as full an implementation of the java.util.List

* objects
*
* the mimicry of List is as follows:
* <ul>
* <li> if possible, operations designated 'optional' in the List
* interface are attempted
* <li> wherever the List interface refers to an Object, substitute
* double
* <li> wherever the List interface refers to a Collection or List,
* substitute DoubleList
* </ul>
*
* the mimicry is not perfect, however:
* <ul>
* <li> operations involving Iterators or ListIterators are not
* supported
* <li> remove(Object) becomes removeValue to distinguish it from
* remove(int index)
* <li> subList is not supported
* </ul>
