Swift Package Manager support

[bryan1anderson]

I'm interested in using modules within my own project and the ability to define this as a dependency package

Package manager support is currently in PR review. Stay tuned :)

The SPM cannot recognize the tag 0.7 version

+1 on not being able to recognize the tag, any updates there? I'd rather not just point to master (which is what I'm doing right now)

Updated the tags for proper SPM parsing. I have tested this in latest Xcode. Proverbial "try now".
