[IronPython] Need a Good Embedded Example

[Michael Foord]

Hello Joshua,

I'll take a look at this.

It is really easy for IronPython 1 and everything has changed for IP 2 
(and the docs are not exactly complete).

It just takes a bit of exploration. You need to be able to set some 
globals in the default module (where you can make your .NET objects 
available to IP code - and then pull the globals back out after 
executing the Python).
