> Add support in the NMS API for users to set an custom MessageTransformer on the NMS object: 
> IConnectionFactory
> IConnection
> ISession
> IMessageProducer
> IMessageConsumer
> The transformer would be an instance of IMessageTransformer which provides two methods:
> {noformat}
>     /// <summary>
>     /// Interface for a class that can Transform a Message from one type to another either
>     /// before consumption or before sent by a producer.
>     /// </summary>
>     public interface IMessageTransformer
>     {
>         /// <summary>
>         /// Called from an IMessageProducer prior to sending the IMessage, allows the client
>         /// to perform a transformation on the Message prior to it being sent.  This allows a
>         /// client to configure a single Producer to convert a Message to a format that can be
>         /// processed by a specific receiving client.
>         /// </summary>
>         IMessage ProducerTransform(ISession session, IMessageProducer producer, IMessage message);
>         /// <summary>
>         /// Called from an IMessageConsumer prior to dispatching the message to the client either
>         /// by the 'Receive' methods or from the async listener event.  Allows the client to perform
>         /// message pre-processing before some messages are dispatched into the client code.
>         /// </summary>
>         IMessage ConsumerTransform(ISession session, IMessageConsumer producer, IMessage message);
>     }
> {noformat}
