[rabbitmq-discuss] cannot redeclare exchange with different type

[Sid Young]

I have been exploring fanout exchanges for a few nights as part of a stock 
graphing system I'm writing and in the process of recreating the exchange 
numerous times via my c++ programs, it appears once created, you need to 
delete it before redefining it as a different type.
