Detailed Description
template<typename I, typename V>
class unique_storage< I, V >
Store values such that only one copy of the value is ever stored.
I is an arbitrary typename that's never used.
It is a required parameter in order to enforce type-safety for a collection.
The value type "V" must be default-constructible, and this is the value returned by a stored id_value where .set() is false
