Yes, you can add a "key" field to the struct, and then define ordered
unique index on it.
Note that when accessing multi_index_container you say explicitly
which index you're working with. So, when you're working with
random_access<> index, you'll get the items in the order of insertion,
but when you switch to another (eg. ordered) index, you get the items
in another order.
