//
// The initialization here is a bit complicated. FindBarBridge is
// created by a static method in BrowserWindow. The FindBarBridge
// constructor creates a FindBarCocoaController, which in turn loads a
// FindBarView from a nib file. All of this is happening outside of
// the main view hierarchy, so the static method also calls
// BrowserWindowCocoa::AddFindBar() in order to add its FindBarView to
// the cocoa views hierarchy.
//
// Memory ownership is relatively straightfoward. The FindBarBridge
// object is owned by the Browser. FindBarCocoaController is retained
// by bother FindBarBridge and BrowserWindowController, since both use it.
