/// <summary>
/// This class mirrors parts of the Assert API from NUnit in a sane way.
/// The problem with NUnit is that stuff like Assert.AreEqual(15, 16) creates allocations behind the scenes, so tests
/// that checks large collections will spend the vast majority of their time just checking their results.
/// You can use this by writing
///    using Assert = FastAssert;
/// at the top of your file. There are some parts of the API that you may need to fix up manually, mainly because this
/// class does not expose overloads like Assert.AreEqual(object a, object b) because that's just asking for pain.
