Ferreteria startup process

This is the chain of events that takes place, in a typical application based on caAppUser ("the App object" or just "App"), when the site is invoked (i.e. a page is requested, possibly just the front page or possibly something more specific).
Assuming there are no initialization problems, App calls its Main() function. This then opens the database and, if successful, calls its GetPageObject() method to get the Page object to use for rendering. The class to used is determined by the Ferreteria deployment's configuration, and is not (at least by default) affected by the URI data.
App->Main() then calls the Page object's DoBuilding(), DoFiguring(), and DoOutput() methods. Each of those then creates an appropriate evint object and passes it to $this->DoEvent():
- DoBuilding(): cEventNodeBuild
- DoFiguring(): cEventNodeFigure
- DoOutput() actually calls $this->Render() which calls $this->RenderNodes() which must be defined by the Page object. The standard implementation is to use the tRenderableTree trait, which then iterates through each sub-node... this doesn't quite make sense. At what point is the Render event created?
