Yes, you are right. In it comments, it says container means random access
container. Maybe array and list are less used in development. I still
consider it's necessary to make them available for d-ary in the new library.
So I want to rebuild d_ary_heap.hpp by using iterator in the new library.
Will that be redundancy for Boost?

Besides, my understanding on "A second requirement is that heaps may be
"mutable", meaning that a value already stored in the heap can be modified
and the heap efficiently updated to accommodate the new change" is that we
can modify all the nodes in the key, not just the root. If my understanding
was right, there would be the other reason to include d-ary in the new
library becuse the original one in the BGL dose not support this operation (
operation update in d_ary_heap.hpp is only for root).

Thank you for your time.
Yours sincerely,
Tao Lin
