    Efficient data structure for manipulating HTTP headers.

    A :class:`list` of ``(name, values)`` is inefficient for lookups.

    A :class:`dict` doesn't suffice because header names are case-insensitive
    and multiple occurrences of headers with the same name are possible.

    :class:`Headers` stores HTTP headers in a hybrid data structure to provide
    efficient insertions and lookups while preserving the original data.

    In order to account for multiple values with minimal hassle,
    :class:`Headers` follows this logic:

    - When getting a header with ``headers[name]``:
        - if there's no value, :exc:`KeyError` is raised;
        - if there's exactly one value, it's returned;
        - if there's more than one value, :exc:`MultipleValuesError` is raised.

    - When setting a header with ``headers[name] = value``, the value is
      appended to the list of values for that header.

    - When deleting a header with ``del headers[name]``, all values for that
      header are removed (this is slow).

    Other methods for manipulating headers are consistent with this logic.

    As long as no header occurs multiple times, :class:`Headers` behaves like
    :class:`dict`, except keys are lower-cased to provide case-insensitivity.

    Two methods support manipulating multiple values explicitly:

    - :meth:`get_all` returns a list of all values for a header;
    - :meth:`raw_items` returns an iterator of ``(name, values)`` pairs.
