 <p>Often, many of the pieces needed for writing network applications can be
 reused across multiple services. The <code>Layer</code> trait can be used to write
 reusable components that can be applied to very different kinds of services;
 for example, it can be applied to services operating on different protocols,
 and to both the client and server side of a network transaction.</p>

 <p>The above log implementation is decoupled from the underlying protocol and
 is also decoupled from client or server concerns. In other words, the same
 log middleware could be used in either a client or a server.</p>
