Platform.io Support

[bshambaugh]

(Issue Summary / Feature Request)

I started playing around with your Blink sketch and I realized that it was not easily portable to platform.io . /home/Arduino, library.properties, and a specific folder structure were assumed. Is there an easy way to think about migration? I included a link to my Platform.io attempt.
