/**
 * DrainC provides a many-to-one collection routing service.
 * <p>
 * Use the SendMsg interface to send a message up the tree.
 * <p>
 * Why does DrainC provide SendMsg instead of Send? Because it provides an
 * argument for a destination address. This will eventually be used to
 * select between multiple trees when sending a message, but for now,
 * it is used to decide whether to send a message up the tree, to the
 * link-local broadcast address, or to the local serial connection.
 * <p>
 * TOS_DEFAULT_ADDR means "the tree" (defined in Drain.h) <br>
 * TOS_BCAST_ADDR means "the link-local broadcast" <br>
 * TOS_UART_ADDR means "the serial connection" <br>
 * <p>
 * All messages will contain the Drain header.
 * <p>
 * The Send interface is also provided because it provides getBuffer().
 * Don't use Send.send().
 * <p>
 * The Receive interface doesn't do anything currently, but will
 * eventually be used to deliver messages that have been routed down
 * the tree from the root.
 * <p>
 * Intercept and Snoop have the usual meanings.
 * <p>
 * NOTE: Drain provides three Nucleus attributes for status
 * reporting. You do not have to include the Nucleus system to use
 * Drain, but to compile it, you must make sure that the Nucleus
 * directory is in the include path, so Attrs.h can be found.
