/**
 * Creates a new folder resource in the selected container and with the
 * selected name. Creates any missing resource containers along the path;
 * does nothing if the container resources already exist.
 * <p>
 * In normal usage, this method is invoked after the user has pressed Finish
 * on the wizard; the enablement of the Finish button implies that all
 * controls on this page currently contain valid values.
 * </p>
 * <p>
 * Note that this page caches the new folder once it has been successfully
 * created; subsequent invocations of this method will answer the same
 * folder resource without attempting to create it again.
 * </p>
 * <p>
 * This method should be called within a workspace modify operation since it
 * creates resources.
 * </p>
 * 
 * @return the created folder resource, or <code>null</code> if the folder
 *         was not created
