I'm confused about the default namespace setting in the project
properties.  Help has the following:

"Default namespace
Specifies the base namespace for all files in the project. For example,
if you set the root namespace to Project1 and you have a Class1 outside
of any namespace in your code, its namespace would be Project1.Class1.
If you have a Class2 within a namespace Order in code, its namespace
would be Project1.Order.Class2."

This would imply if I have

namespace Foo{
class Bar{...}
}

And set my default namespace to "Grand", then I thought my class should
appear as Grand.Foo.Bar, but it seems to just be Foo.Bar

So I'm not at all sure now what the default namespace does.
