    \class QMessageContentContainer

    \brief The QMessageContentContainer class provides an interface for internet media (MIME) 

    and Transport Neutral Encapsulation Format (TNEF) content that is possibly only 

    partially retrieved.

    \ingroup messaging

    A QMessageContentContainer object can either directly contain media such as text, 

    image, audio, video, application or message data, or contain multiple parts of content, 

    but can not contain both media and multiple parts directly.

    Container objects can be obtained via their QMessageContentContainerId 

    identifier, using the find() function of the containing QMessage object.

    For textual content using a recognized charset encoding textContent() will 

    return the content as a unicode string.

    For non-multipart content content() will return the content data after decoding any 

    transfer encoding used to represent binary data using 7-bit ASCII characters, such as 

    quoted-printable and base64.

    The internet media (MIME) type of the container is returned by contentType(),

    the content subtype is returned by contentSubType(), the content type charset parameter 

    is returned by contentCharset(), and the content suggested filename by suggestedFileName(). 

    The type of a container that contains multiple parts of content must be "multipart" (case 

    insensitive).  A list of identifiers for directly contained parts of content is returned 

    by contentIds().

    An indication of the size of the container and its contents on the originating server is 

    given by size(). If the content is entirely available on the device 

    isContentAvailable() will return true.

    Non-multipart content can be serialized to a QDataStream using 

    writeContentTo(), or to a QTextStream using writeTextContentTo().

    A container also stores name-value pairs known as header fields. Names are ASCII strings, 

    while values are charset encoded unicode strings.  A list of the header fields present 

    in a container is returned by headerFields(). The unicode string values associated 

    with a particular header field name are returned by headerFieldValues().

    \fn QMessageContentContainer::contentType() const

    Returns the content type of the container. Common types are "text", "image", "audio", 

    "video", "application", "message" and "multipart".

    The internet media (MIME) type of the container is "multipart" if the container directly 

    contains multiple parts rather than directly contains media.

    \fn QMessageContentContainer::contentSubType() const

    Returns the internet media (MIME) subtype of the content.

/*!

    \fn QMessageContentContainer::contentCharset() const

    Returns the internet media (MIME) content charset, when defined; 

    otherwise an empty array is returned.

/*!

    \fn QMessageContentContainer::suggestedFileName() const

    Returns the suggested filename for the attachment, when defined;

    otherwise an empty array is returned.

    The default is an empty array.

/*!

    \fn QMessageContentContainer::isContentAvailable() const

    Returns true if the entirety of the content contained is available on the device; 

    otherwise returns false.

*/

/*!

    \fn QMessageContentContainer::size() const

    If the size of the container is known then returns an indication of the size of the container 

    on the originating server, including contents; otherwise returns 0.

    \fn QMessageContentContainer::textContent() const

    For textual content encoded with a recognized charset, returns the content as a unicode string; 

    otherwise a null string is returned.

*/

/*!

    \fn QMessageContentContainer::content() const

    Return the content after decoding any transfer encoding used to represent binary data 

    using 7-bit ASCII characters, such as quoted-printable and base64.

    For textual content any text charset encoding such as Shift-JIS, ISO 2022-JP, KOI8-R, 

    Windows-1251 etc will not be decoded.

/*!

    \fn QMessageContentContainer::writeContent(QDataStream& out) const

    For a non-multipart container, writes the content as returned by content() 

    to the stream \a out; otherwise does nothing.
