 *  @var RelationType RELATION_NULL
 * Not used, represens "no relationship" or an error condition.
 * 
 *  @var RelationType RELATION_CONTROLLED_BY
 * Indicates an object controlled by one or more target objects.
 * 
 *  @var RelationType RELATION_CONTROLLER_FOR
 * Indicates an object is an controller for one or more target objects.
 * 
 *  @var RelationType RELATION_LABEL_FOR
 * Indicates an object is a label for one or more target objects.
 * 
 *  @var RelationType RELATION_LABELLED_BY
 * Indicates an object is labelled by one or more target objects.
 * 
 *  @var RelationType RELATION_MEMBER_OF
 * Indicates an object is a member of a group of one or more target objects.
 * 
 *  @var RelationType RELATION_NODE_CHILD_OF
 * Indicates an object is a cell in a treetable which is displayed because a cell in the same column is expanded and identifies that cell.
 * 
 *  @var RelationType RELATION_FLOWS_TO
 * Indicates that the object has content that flows logically to another
 * AtkObject in a sequential way, (for instance text-flow).
 * 
 *  @var RelationType RELATION_FLOWS_FROM
 * Indicates that the object has content that flows logically from
 * another AtkObject in a sequential way, (for instance text-flow).
 * 
 *  @var RelationType RELATION_SUBWINDOW_OF
 * Indicates a subwindow attached to a component but otherwise has no connection in  the UI heirarchy to that component.
 * 
 *  @var RelationType RELATION_EMBEDS
 * Indicates that the object visually embeds 
 * another object's content, i.e. this object's content flows around 
 * another's content.
 * 
 *  @var RelationType RELATION_EMBEDDED_BY
 * Inverse of Atk::RELATION_EMBEDS, indicates that
 * this object's content is visualy embedded in another object.
 * 
 *  @var RelationType RELATION_POPUP_FOR
 * Indicates that an object is a popup for another object.
 * 
 *  @var RelationType RELATION_PARENT_WINDOW_OF
 * Indicates that an object is a parent window of another object.
 * 
 *  @var RelationType RELATION_DESCRIBED_BY
 * Indicates that another object provides descriptive information about this object; more verbose than ATK_RELATION_LABELLED_BY.
 * 
 *  @var RelationType RELATION_DESCRIPTION_FOR
 * Indicates that an object provides descriptive information about another object; more verbose than ATK_RELATION_LABEL_FOR.
 * 
 *  @var RelationType RELATION_NODE_PARENT_OF
 * Indicates an object is a cell in a treetable and is expanded to display other cells in the same column.
