title: NSubstitute VerifyAll equivalent
body: <p>Does NSubstitute have an equivalent to MOQ's <code>VerifyAll</code> call? I'd like to verify that all calls I expect to be received across all substitutes are actually called, ideally in a single <code>TearDown</code> method. I'm currently verifying each received call individually in tests, which isn't ideal. For starters, any calls that are set up on the substitute but that then don't actually get called would slip through the net if they weren't explicitly verified individually.</p>
