 // A BrowserPluginEmbedder has a list of guests it manages.
 // In the beginning when a renderer sees one or more guests (BrowserPlugin
 // instance(s)) and there is a request to navigate to them, the WebContents for
 // that renderer creates a BrowserPluginEmbedder for itself. The
 // BrowserPluginEmbedder, in turn, manages a set of BrowserPluginGuests -- one
 // BrowserPluginGuest for each guest in the embedding WebContents. Note that
 // each of these BrowserPluginGuest objects has its own WebContents.
 // BrowserPluginEmbedder routes any messages directed to a guest from the
 // renderer (BrowserPlugin) to the appropriate guest (identified by the guest's
 // |instance_id|).
 //
 // BrowserPluginEmbedder is responsible for cleaning up the guests when the
 // embedder frame navigates away to a different page or deletes the guests from
 // the existing page.
