Remarks

• Intended for use as a base class of polymorphic classes: A template-based approach without virtual destructor is preferred for non-polymorphic classes for efficiency.
• Count value made mutable and reference add/subtract functions made const so that const objects can be held by shared ownership smart pointers.
• Prefer to ReferenceCountMI if single inheritance is being used and a pure interface is not needed at the top of the hierarchy since the counter update functions are non-virtual here.
