It defines everything necessary for the Hubzilla application: Server variables, URL arguments, page structures, layouts, content, installed plugins, output device info, theme info, identity of the observer and (potential) page owner ... We don't ever create more than one instance and always modify the elements of the single instance. The mechanics of this are somewhat tricky.
