Create a `function` having the same value as (i.e., wrapping a copy of the target held by) the specified `original` object. Use the specified `allocator` (e.g., the address of a `bslma::Allocator` object) to supply memory. If `allocator == original.allocator()`, this object is created as if by move construction; otherwise it is created as if by extended copy construction using `allocator`.
