Add CocoaPods support

[zoul]

Self-note: see zoul/Lambda-Alert#7 for a quick howto.

The repository now contains a podspec, the remaining work to do is to verify that the thing works as expected and add the library to the official CocoaPods repository.

Sorry for being late, I'll take care of that.

The lib is so great to not be on cocoapods =)
Thanks for your great work @zoul!

Still can't find it on cocoapods, what's the status on this? :)

[marlonandrade]

@M0rph3v5 there's a podspec that is just outdated, but it's pointing to master, so it should work.

I've stopped working on the project that was using Finch, so I didn't test 1.0.0 and thought that I should not add it to the cocoapods specs repo without testing.

The podspec needs to be upgrade to point to tag 1.0.0 and add to the CocoaPods/Specs repo in order to be able to install with pod install Finch.

For now you have some options:

1. Use the podspec as a local pod:
   pod 'Finch', :path => 'your local path to Finch repo'
2. Or: point to the git Finch repo:
   pod 'Finch', :git => 'https://github.com/zoul/Finch'
3. Or: use it as a Private pod

If you do any of those 3 and verify that the podfile is correct and test the lib, I sugest to make a pull request to the Specs repo in order to add it to the original cocoapods repo.

[M0rph3v5]

Yeah I found out you could do that just now (did option 2), seems to be working fine here. I'll see if I have time to test a little further and do the pr to cocoapods.

By a coincidence I just added CocoaPods support to some of my other libraries, so it should not be a problem to add it to Finch, too. During this weekend, probably.

[M0rph3v5]

In that case I'll let you sort it out, let me know once it's in there :)

I have submitted a fresh 1.0.0 release PR to the Specs repo. Once the PR is merged, I would welcome if somebody could test that the pod really works (integrates into an Xcode project and builds).
