Just updated the NeoPixel library to support Mesh devices (Argon, Boron and Xenon) thanks to @cullenshane @jvanier @bsatrom @JamesHagerman 
Important:
If you have an old app that you would like to update please remove the NeoPixel library from your app and re-apply it to update the included library to v1.0.0. If you are creating a new app, simply add the NeoPixel library to your app and you will have the latest v1.0.0.
