docs: Function: start
  On start on the server, this function creates an <APIAdapter> if apiRoutes
  are present in the startOptions. Further the actual <Barefoot.Router> is
  created an started using <Barefoot.Router.Server.start>.
  
  Before doing all this, startOptions is checked if an Express.JS app is
  present (if not, an error gets thrown which will stop the start process).
  
  Parameters:
  (Barefoot.Router) Router - A <Barefoot.Router> object. Important: This is
  is not an instance of the router, it is the
  "plain" object which can be used for running
  "new Router(...)".
  (Object) startOptions - This object literal is passed to the router when
  initializing it.
