Update to support Swift 2.3

[piercifani]

Hello guys!

This is for those of us who need Swift 2.3 support ASAP to keep using this awesome framework.

There is a lot of noise because the Pods are in the repo, but the only changes you are interested are in Source/RouteMatcher.swift and in Source/Route.swift

Cheers 🍷

Whoa, I didn't notice there was one PR already out there. My bad. Chose whatever you feel more confortable with!

@piercifani thank you for taking the time. Sorry for the delay with swift 2.3 and 3.0 (WIP) . Due to holidays and now NSSpain we couldn't make it in time.
Swift 2.3 is completed but we have troubles with the CI, I hope to solve them this weekend and then release a swift 2.3 version (same for 3 during next week)
If you managed to solve those problems already I would be happy to merge it.

@piercifani hey! the other branch is ready (but #114 ) we also needed to do #117 because it requires a major version release so we won't merge this PR. But thank you for the time spent and we appreciate your contribution.
