virtual bool	IsMappable () const
	Derived, typed classes tell whether the on-storage layout is bitwise identical to the memory layout.

RColumnElementBase &	operator= (RColumnElementBase &&other)=default

virtual void	Pack (void destination, void source, std::size_t count) const
	If the on-storage layout and the in-memory layout differ, packing creates an on-disk page from an in-memory page.

virtual void	Unpack (void destination, void source, std::size_t count) const
	If the on-storage layout and the in-memory layout differ, unpacking creates a memory page from an on-storage page.
