Overview
The EISCP::Receiver class is used to communicate with one or more receivers the network. A Receiver can be instantiated automatically using discovery, or by hostname and port.
receiver = EISCP::Receiver.new # find first receiver on LAN
receiver = EISCP::Receiver.new('192.168.1.12') # default port
receiver = EISCP::Receiver.new('192.168.1.12', 60129) # non standard port

#initialize(host = nil, info_hash = {}, &block) ⇒ Receiver
Create a new EISCP::Receiver object to communicate with a receiver. If no host is given, use auto discovery and create a receiver object using the first host to respond.
