See the example at http://www.rabbitmq.com/api-guide.html for usage of 
the builder classes. You may also want to read up on the builder pattern 
in general. The mistake in the above is that basicPublish is invoked 
with the plain props object constructed in the first line, rather than 
the object produced by the builder.
