示例1: findPageToRender
// Given a request, follow the segments through sitetree to find the page that is being requested. Doesn't
// understand actions, so just finds the page. Returns ID of SiteTree_Live record or 0 if it can't find a
// matching page.
// @todo Understand BaseController actions, or break on the furthest it gets up the tree
// @todo cache site tree
