  * Add a compileToCore function to the GHC API
  
  Added a compileToCore function to the GHC API that takes a
    session, module, and filename, and returns a list of Core
    bindings if successful. This is just a first try and could
    probably be improved (for example, there's probably a way to
    get the filename from the module so that it doesn't have to 
    be passed in, I just don't see it offhand.)
