Indirection stub settings for the instance method of an internal class generates build errors.

[urasandesu]

In Prig v0.0.0-alpha8, when making the indirection stub settings like the following class, build errors occurred:

internal class FooInternal
{
    public void DoIt()
    {
        throw new NotImplementedException();
    }
}

It seems that the signature of the method DoIt is public seemingly. However, it requires implicit this parameter. The type of this is FooInternal, so the member's signature is non-public in fact.

Prig should avoid to make the indirection stub of such member automatically.
