+Package channel provides helper structs/methods/funcs for working with channels
+
+Proxy from an io.Writer to a channel:
+
+	w := channel.NewWriter(make(chan []byte, 10))
+	go func() {
+		w.Write([]byte("Hello, World"))
+	}()
+
+	fmt.Println(string(<-w.Chan()))
+    w.Close()
+
+Use of the constructor is required to initialize the channel.
+Provide a channel of sufficient size to handle messages from writer(s).
