-SQS Message
-
-A Message represents the data stored in an SQS queue.  The rules for what is allowed within an SQS
-Message are here:
-
-    http://docs.amazonwebservices.com/AWSSimpleQueueService/2008-01-01/SQSDeveloperGuide/Query_QuerySendMessage.html
-
-So, at it's simplest level a Message just needs to allow a developer to store bytes in it and get the bytes
-back out.  However, to allow messages to have richer semantics, the Message class must support the
-following interfaces:
-
-The constructor for the Message class must accept a keyword parameter "queue" which is an instance of a
-boto Queue object and represents the queue that the message will be stored in.  The default value for
-this parameter is None.
-
-The constructor for the Message class must accept a keyword parameter "body" which represents the
-content or body of the message.  The format of this parameter will depend on the behavior of the
-particular Message subclass.  For example, if the Message subclass provides dictionary-like behavior to the
-user the body passed to the constructor should be a dict-like object that can be used to populate
-the initial state of the message.
-
-The Message class must provide an encode method that accepts a value of the same type as the body
-parameter of the constructor and returns a string of characters that are able to be stored in an
-SQS message body (see rules above).
-
-The Message class must provide a decode method that accepts a string of characters that can be
-stored (and probably were stored!) in an SQS message and return an object of a type that is consistent
-with the "body" parameter accepted on the class constructor.
-
-The Message class must provide a __len__ method that will return the size of the encoded message
-that would be stored in SQS based on the current state of the Message object.
-
-The Message class must provide a get_body method that will return the body of the message in the
-same format accepted in the constructor of the class.
-
-The Message class must provide a set_body method that accepts a message body in the same format
-accepted by the constructor of the class.  This method should alter to the internal state of the
-Message object to reflect the state represented in the message body parameter.
-
-The Message class must provide a get_body_encoded method that returns the current body of the message
-in the format in which it would be stored in SQS.
