title: Error when Building Project: Error building Player because scripts have compile errors in the editor
body: <p>I have the Tiled2Unity plugin. When I begin to build a version of my game in Unity, be it standalone version or anything else,i  get the following error, "Error building Player because scripts have compile errors in the editor"</p>
  
  <p>Then it points me to this class</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  
  using UnityEditor;
  
  namespace Tiled2Unity
  {
      public class CircleObject : TmxObject
      {
      }
  }
  </code></pre>
  
  <p>Can someone please help me figure out what is the problem?</p>
