 * SpoutMsg is an object that represents the data sent from a shell spout to a process that implements a multi-language spout. The SpoutMsg is used to send a

 * 
 * <p>
 * Spout messages are objects sent to the ISerializer interface, for serialization according to the wire protocol implemented by the serializer. The SpoutMsg
 * class allows for a decoupling between the serialized representation of the data and the data itself.
