 * <p>
 * AssessmentManager handles creating and deleting:
 * 
 * <ul>
 * <li>
 * Assessment,
 * </li>
 * <li>
 * AssessmentPublished,
 * </li>
 * <li>
 * Item,
 * </li>
 * <li>
 * Section;
 * </li>
 * </ul>
 * 
 * and getting:
 * 
 * <ul>
 * <li>
 * Assessment,
 * </li>
 * <li>
 * AssessmentPublished,
 * </li>
 * <li>
 * Item,
 * </li>
 * <li>
 * Section,
 * </li>
 * <li>
 * various implementation Types.
 * </li>
 * </ul>
 * </p>
 * 
 * <p>
 * All implementations of OsidManager (manager) provide methods for accessing
 * and manipulating the various objects defined in the OSID package. A manager
 * defines an implementation of an OSID. All other OSID objects come either
 * directly or indirectly from the manager. New instances of the OSID objects
 * are created either directly or indirectly by the manager.  Because the OSID
 * objects are defined using interfaces, create methods must be used instead
 * of the new operator to create instances of the OSID objects. Create methods
 * are used both to instantiate and persist OSID objects.  Using the
 * OsidManager class to define an OSID's implementation allows the application
 * to change OSID implementations by changing the OsidManager package name
 * used to load an implementation. Applications developed using managers
 * permit OSID implementation substitution without changing the application
 * source code. As with all managers, use the OsidLoader to load an
 * implementation of this interface.
