Returns true if the candidate object is logically equal. Logical
 equivalence is true if the lat and lng attributes are the same for both
 objects.
 Equivalent to Google Maps API's .toSpan() method on GLatLng's.

 Returns a LatLng object, whose coordinates represent the size of a
 rectangle defined by these bounds.
