title: ZeroMQ Topic Filtering with Pub/Sub (Java binding)
body: <p>How can I get ZeroMQ to support topics and pattern matching?</p>
  
  <p>e.g.</p>
  
  <pre><code>stocks.*
  stocks.appl
  </code></pre>
  
  <p>From my understanding ZeroMQ..the topic will be part of the message so I need someway of separating the topic from the actual message in the subscriber.
  Whats the best way of separating the topic and message? Do you need a special character (e.g. SOH)?</p>
