 * @class ListOf
 * @sbmlbrief{core} Parent class for libSBML's "ListOfXYZ" classes.
 *
 * @htmlinclude not-sbml-warning.html
 *
 * The ListOf class in libSBML is a utility class that serves as the parent
 * class for implementing the ListOf__ classes.  It provides methods for
 * working generically with the various SBML lists of objects in a program.
 * LibSBML uses this separate list class rather than ordinary
 * @if conly C@endif@if cpp C++; @endif@if java Java@endif@if python Python@endif@~ lists,
 * so that it can provide the methods and features associated with SBase.
 *
 * Whether a given ListOf element may be empty or not depends on the 
 * element in question, and on what level and version of SBML it
 * is being used for.  For ListOf elements in SBML Level&nbsp;3
 * Version&nbsp;1 and prior, no core list and few package lists could
 * be empty.  As of SBML Level&nbsp;3 Version&nbsp;2, the rules
 * were relaxed, and lists were allowed to be empty.  In libSBML,
 * documents created for Level&nbsp;3 Version&nbsp;2 will be written
 * with empty ListOf's if that ListOf contains some other 'extra'
 * information: an attribute such as metaid or sboTerm, a child
 * '&lt;notes&gt;' or '&lt;annotation&gt;', or information from a SBML 
 * Level&nbsp;3 package.
