Libraries and Include Files

[avose]

Thanks so much for this wonderful project! I finally have things all built and ready to try out.

I did need to move all the source code files in "lib/" out of their sub-directories and place them into the "src/" directory for the Arduino IDE (v2.2.1 on Ubuntu Linux) to see them. Then I needed to change some #include directives to use quotes instead of angle brackets, and had to fix a couple "helpers.h" includes which need to be "Helpers.h" in Linux due to the filesystem being case sensitive.

It might be worth at least fixing the "helpers.h" / "Helpers.h" issue, and it would be super cool if the directory structure could be fixed somehow so that things work out of the box without having to move the files around.

Anyway, thanks much for the great project!!
