<h2>CollectionAssert (NUnit 2.4 / 2.5)</h2>
<p>The CollectionAssert class provides a number of methods that are useful
when examining collections and their contents or for comparing two collections.</p>
<p>The <b>AreEqual</b> overloads succeed if the corresponding elements of the two
collections are equal. <b>AreEquivalent</b> tests whether the collection contents
are equal, but without regard to order. In both cases, elements are compared using
NUnit's default equality comparison.</p>
<p>Beginning with NUnit 2.4.6, these methods may be used on any object that
implements IEnumerable. Prior to 2.4.6, only true collections were supported.
