Visual Basic command parser example

OK, I left the Visual Basic version of this code as an "exercise for the reader," but it turned out that I needed it myself. I translated (by hand) the C# example but couldn't get the Visual Basic version to find the method in the InvokeMember call (even after the FindMembers call had found it). I poked around some more, thinking that once I had the MethodInfo I should be able to use it directly without having to use InvokeMember.

Sure enough, after poking around a bit I found Invoke (on the MethodInfo itself), and it works like a charm.

Maybe some day when I'm feeling more ambitious I'll go back and rework the C# example to match the Visual Basic example, but probably not until I really need to. I actually hope I don't, because that means that I will have a need to use C#, and I'd rather stay cross-platform with something like Java, C++ or Python.
