Swift 3 Warnings

[jewilhel]

When I imported this framework. I noticed about 8 warning messages in the framework that I believe are Swift 3 language change issues. Hopefully I can fix them and use the framework successfully.

Hello @jewilhel , can you specify warning messages please?

[jewilhel]

Yeah, the warnings seemed to be related to:
M_PI is depreciated, use Double.pi or .pi and I was able to get it working after fixing. Sorry for not being more specific about the warnings.

Fixed in master branch. Will be included next release.
