Add Carthage support
- Added dynamic framework targets for OS X and iOS
- Shared and added schemes to repository
Resolves #36
CI failed since it could not install cocoapods. (Which this PR should not affect.)
We don't need a TransitionKit-OSX.h and TransitionKit-iOS.h. This can be streamlined a bit
I agree that it would be preferable to just use the original TransitionKit.h. I wasn't able to find a setting to specify an umbrella or master header that is not identical to the name of the target yet, but I'll give it another shot.
@blakewatters Removed extraneous umbrella headers and streamlined info.plist files.
CI failing because of Ruby version issues, but I am successfully using this branch in my projects.
