/**
 *
 * Drip provides an epidemic dissemination service for single messages.
 * <p>
 * Drip messages are identified using a standard Active Message ID.
 * <p>
 * Incoming messages are received on the Receive interface.
 * <p>
 * Each client of Drip is responsible for caching the message received
 * on the Receive interface, and providing it to the Drip interface
 * when retransmission is necessary.
 * <p>
 * Here is an example wiring you can use with Drip:
 * <p>
 * <tt>
 * TestDripM.ReceiveDrip -> DripC.Receive[AM_TESTDRIPMSG];<br>
 * TestDripM.Drip -> DripC.Drip[AM_TESTDRIPMSG];<br>
 * DripC.DripState[AM_TESTDRIPMSG] -> DripStateC.DripState[unique("DripState")];<br>
 * </tt>
