Simple flooding protocol

Protocol Description
When a node has a message to send, it broadcasts the message. When a node receives a message, it rebroadcasts the message. Each node keeps track of what messages it has seen and only forwards those which it hasn't seen before. Each message is of the form "ID:DATA" where ID is some arbitrary message identifier and DATA is the payload. In order to reduce memory usage, the agent stores only the message ID. There is no mechanism to expire old message IDs from the list of seen messages. There also isn't any mechanism for assigning message IDs.
