template<typename T>
not_null class
A wrapper around a pointer that indicates that it should never be null.
It deletes some operators and assignments from null, but it can only enforce at runtime, via asserts, that the value is not actually null.
The real value of this type is in documenting in the API the intentions of the pointer, so that consumers don't need to add explicit null checks.
