+/// Create a Key-Value Observing helper object.
+///
+/// As long as the returned token object is retained, the KVO notifications of the @c object
+/// and @c keyPath will cause the given @c selector to be called on @c target.
+/// @a object and @a target are weak references.
+/// Once the token object gets dealloc'ed, the observer gets removed.
+///
+/// The @c selector should conform to
+/// @code
+/// - (void)nameDidChange:(NSDictionary *)change;
+/// @endcode
+/// The passed in dictionary is the KVO change dictionary (c.f. @c NSKeyValueChangeKindKey, @c NSKeyValueChangeNewKey etc.)
+///
+/// @returns the opaque token object to be stored in a property
+///
+/// Example:
+///
+/// @code
+///   self.nameObserveToken = [KeyValueObserver observeObject:user
+///                                                   keyPath:@"name"
+///                                                    target:self
+///                                                  selector:@selector(nameDidChange:)];
