 // The AutocompleteController is the center of the autocomplete system.  A
 // class creates an instance of the controller, which in turn creates a set of
 // AutocompleteProviders to serve it.  The owning class can ask the controller
 // to Start() a query; the controller in turn passes this call down to the
 // providers, each of which keeps track of its own matches and whether it has
 // finished processing the query.  When a provider gets more matches or finishes
 // processing, it notifies the controller, which merges the combined matches
 // together and makes the result available to interested observers.
 //
 // The owner may also cancel the current query by calling Stop(), which the
 // controller will in turn communicate to all the providers.  No callbacks will
 // happen after a request has been stopped.
 //
 // IMPORTANT: There is NO THREAD SAFETY built into this portion of the
 // autocomplete system.  All calls to and from the AutocompleteController should
 // happen on the same thread.  AutocompleteProviders are responsible for doing
 // their own thread management when they need to return matches asynchronously.
 //
 // The coordinator for autocomplete queries, responsible for combining the
 // matches from a series of providers into one AutocompleteResult.

Nit: Place this right after the Profile* argument

Done.
