title: Use Debug.Log from C++
body: <p>When making C++ plugins in Unity it is easier to use <a href="https://docs.unity3d.com/ScriptReference/Debug.Log.html" rel="noreferrer"><code>Debug.Log</code></a> to quickly view variable values but this function is only available from C# side. This makes it very hard to debug C++ plugin since Unity's debugger does not support that. <code>std::cout</code> is not an option since it doesn't show in the Editor.</p>
  
  <p>I looked inside the Unity C++ API located at <code>&lt;UnityInstallationDirecory&gt;\Editor\Data\PluginAPI</code> but didn't find anything about logging in the API.</p>
  
  <p>Any suggestions on how to display in the Editor log from C++?</p>
