title: What is Scala's Comparable trait?
body: <p>I am searching for Scala counterpart of C# IComparable, and I found Comparable trait. I mean -- Comparable is mentioned, but when I search for it at <a href="http://www.scala-lang.org/api/current/scala/" rel="noreferrer">http://www.scala-lang.org/api/current/scala/</a> I get 0 hits. Because of the name, using Google I get a lot of "how Scala is comparable to..." results.</p>
  
  <p>Is there any resource I could read about this mysterious Comparable thing? After all Ordered extends it, so it has to exist.</p>
