Create a queue having the value of the specified `original` (on entry), that uses `basicAllocator` to supply memory. The allocator‐extended move constructor of `CONTAINER` is used to create the new queue. `original` is left in a valid but unspecified state. Note that a `bslma::Allocator *` can be supplied for `basicAllocator` if the (template parameter) `ALLOCATOR` is `bsl::allocator` (the default). Also note that this method assumes that `CONTAINER` has a move constructor. Also note that if `CONTAINER::allocator_type` does not exist, this constructor is disabled.
