title: How to register custom build Autofac.Module in Orchard?
body: <p>I have a piece of code that encapsulates functionality that isn't specific to Orchard. However i need to make it available in Orchard via dependency injection. So, I built up an Autofac Module that registers all components (types), but I can't find a way to inform Orchard's Autofac Container about it. </p>
  
  <p>From what i red, there are two ways to add a module to a container:</p>
  
  <p>By supplying the module at to the ContainerBuilder (usually at start-up), 
  Or by updating the already built Container at runtime with a ContainerBuilder</p>
  
  <p>I can approach the problem in the first way, but I rather do a variant of the second if there is such?</p>
