Design logo for UnityLibrary

[agarcialeon]

Currently the README file of this repository doesn't contain a logo for the library. It could be great to have a custom logo for our repository and give it more visibility.

some random ideas:

• using some easily recognizable unity objects, like default unity skybox, unity capsule, play button, empty default icon slot (none of those are really pretty or cool though)
• using actual unity logo, if try to ask permission https://unity3d.com/legal/branding_trademarks
• animated gif of something from unity editor?
