Make example project consume pod via Podfile again.

I know this looks like a big PR, but all I did is remove the duplicate Luhn.h and Luhn.m in the example project and move its contents to the other copies in Algorithm Class which is where the podspec is looking for the files. (So the new stuff you wrote today is in now in the Algorithm Class directory.)

You don't need to worry about keeping the old copies of the Luhn classes because Cocoapods uses git tags to keep track of which version to use.

When you pull this, make sure to run pod install from the Example Project directory. I've made sure the example app and tests run.

Let me know if you have any questions!

@ayanonagon completely understand, I'm going to test it just to make sure, but great work.

Woo hoo! When you feel like releasing v1.1.0, it might be good to rename Algorithm Class to something like ObjectiveLuhn and point the podspec source to that. Great work with the card detection stuff. 👍

Thanks, will do, plan on doing it this weekend if I get a chance :)
