 * An abstract class for a class implementing a basic list in which the most
 * important operations of the List interface are supported, but all others are
 * not supported and result in errors if called. Dummy methods for unsupported
 * operations are defined here. Classes that extend SimpleList must implement
 * all of the remaining List methods not defined in this class. Note that
 * subclasses *can* override and implement any of the methods defined here if
 * they want to support them.

 * @param <T>
 *          The type of object stored by the list.
