Conflicts with Unity Engine.

[Domvel]

I just installed this package (by github download and copied the lib folder).
Now many errors are displayed like (similar text)

unity editor popupfield.cs system.func is defined multiple times

After removed this plugin. All errors are gone.

Unity: 2018.2.9f1

Related to #33

To remove data from C:\Users\<me>\AppData\Local\Unity does not help.

This is a problem with the newest 2018 builds of the Unity Engine.
Unfortunately renders this great library useless :(

Is the creator of the project going to address this issue? I would like to use this for a small project I'm doing with Unity, but it's unusuable right now.
