/**
 * On-site toolbar service.
 *
 * This service manages the toolbars used for the on-site administration system.
 * For each context, it provides the following set of toolbars:
 *
 * 1. The <i>Node</i> toolbar is applicable to the current
 *    node, which is usually a topic. MidCOM places the topic management operations
 *    into this toolbar, where applicable.
 *
 * 2. The <i>View</i> toolbar is applicable to the specific view ("url"). Usually
 *    this maps to a single displayed object (see also the bind_to_object() member
 *    function). MidCOM places the object-specific management operations (like
 *    Metadata controls) into this toolbar, if it is bound to an object. Otherwise,
 *    this toolbar is not touched by MidCOM.
 *
 * It is important to understand that the default toolbars made available through this
 * service are completely specific to a given request context. If you have a dynamic_load
 * running on a given site, it will have its own set of toolbars for each instance.
 *
 * In addition, components may retrieve a third kind of toolbars, which are not under
 * the general control of MidCOM, the <i>Object</i> toolbars. They apply to a single
 * database object (like a bound <i>View</i> toolbar). The usage of this kind of
 * toolbars is completely component-specific.
 *
 * <b>Implementation notes</b>
 *
 * It has yet to prove if the toolbar system is needed for a dynamic_load environments.
 * The main reason for this is that dl'ed stuff is often quite tight in space and thus cannot
 * display any toolbars in a sane way. Usually, the administrative tasks will be bound to the
 * main request.
 *
 * This could be different for portal applications, which display several components on the
 * welcome page, each with its own management options.
 *
 * <b>Configuration</b>
 * See midcom_config for configuration options.
 *
