C# Class LCM.LCM.UDPMulticastProvider

LCM provider for the udpm: URL. All messages are broadcast over a pre-arranged UDP multicast address. Subscription operations are a no-op, since all messages are always broadcast. This mechanism is very simple, low-latency, and efficient due to not having to transmit messages more than once when there are multiple subscribers. Since it uses UDP, it is lossy.
