[Python.NET] exposing modules

Haran - you can't expose a 'module' (in the Python sense), but 
you can easily do what you trying to do.

The usual pattern for this would be stow away a reference to your 
application object in a static where the Python code can then get 
it. Assuming you have an assembly 'my.app', this would look like:

namespace my.app {

  public class MyApp {

  public static MyApp theapp;

    public MyApp() {
      // do initialization
      theapp = this;



Now from Python you can do the following:

from my.app import MyApp
app = MyApp.theapp

hope this helps,
