title: IronPython exposing .Net type to the runtime engine
body: <p>I'm looking to expose specific .Net types to the IronPython runtime.  I can do this:</p>
  
  <pre><code>ScriptEngine engine = Python.CreateEngine();
  ScriptScope scope = engine.CreateScope();
  engine.Runtime.LoadAssembly(typeof(Program).Assembly); // current assembly with types
  </code></pre>
  
  <p>But that exposes <em>all</em> types to the runtime.  Is selective type loading possible?</p>
