title: How to get MethodInfo of interface method, having implementing MethodInfo of class method?
body: <p>I have a <code>MethodInfo</code> of an <em>interface</em> method and <code>Type</code> of a <em>class</em> that implements the <em>interface</em>.
  I want to find the <code>MethodInfo</code> of the class method that implements the interface method.</p>
  
  <p>The simple <code>method.GetBaseDefinition()</code> does not work with interface methods.
  Lookup by name won't work either, because when implementing interface method explicitly it can have any name (yes, not in C#).</p>
  
  <p>So what is the <em>correct</em> way of doing that that covers all the possibilities?</p>
