Create a multimap and insert each `value_type` object in the specified `values` initializer list. Optionally specify a `comparator` used to order keys contained in this object. If `comparator` is not supplied, a default‐constructed object of the (template parameter) type `COMPARATOR` is used. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is not supplied, a default‐constructed object of the (template parameter) type `ALLOCATOR` is used. If the type `ALLOCATOR` is `bsl::allocator` (the default), then `basicAllocator`, if supplied, shall be convertible to `bslma::Allocator *`. If the type `ALLOCATOR` is `bsl::allocator` and `basicAllocator` is not supplied, the currently installed default allocator is used. If `values` is ordered according to `comparator`, then this operation has `O[N]` complexity, where `N` is the number of elements in `values`; otherwise, this operation has `O[N * log(N)]` complexity. This method requires that the (template parameter) types `KEY` and `VALUE` both be `copy‐insertable` into this multimap (see {Requirements on `KEY` and `VALUE`}).
