    VCR's  representation of a request.

    There is a weird quirk in HTTP.  You can send the same header twice.  For
    this reason, headers are represented by a dict, with lists as the values.
    However, it appears that HTTPlib is completely incapable of sending the
    same header twice.  This puts me in a weird position: I want to be able to
    accurately represent HTTP headers in cassettes, but I don't want the extra
    step of always having to do [0] in the general case, i.e.
    request.headers['key'][0]

    In addition, some servers sometimes send the same header more than once,
    and httplib *can* deal with this situation.

    Futhermore, I wanted to keep the request and response cassette format as
    similar as possible.

    For this reason, in cassettes I keep a dict with lists as keys, but once
    deserialized into VCR, I keep them as plain, naked dicts.
