||This extension adds Soft and Weak references support to PHP 7 and may serve as a ground for other data structures that require advanced referencing model.
|- fixes problem when false Ref\NotifierException thrown during object destruction if non-caught exception
was thrown before such destruction (outside notifiers and referent object destructor) (#17);
- do not call soft notifiers if original object was prevented from being destroyed in one of notifiers (#18).
