module RETS

For more information on what the possible values of fields that are passed to the RETS server can be, see {www.rets.org/documentation}.

This is a slightly crazy hack, but it's saner if we can just use Net::HTTP and then fallback on the StreamHTTP class when we need to do stream parsing. If we were to do it ourselves with Sockets, it would be a bigger pain to manage that, and we would have to do roughly the same setup as below anyway. Essentially, for the hack of using instance_variable_get/instance_variable_set, we get a simple stream parser, without having to write our own HTTP class.
