Creates a const reference wrapper. Passing an object throught sigc::ref() makes libsigc++ adaptors like, e.g., sigc::bind store references to the object instead of copies. If the object type inherits from sigc::trackable this will ensure automatic invalidation of the adaptors when the object is deleted or overwritten.
