allow show without func Show

[aiden-leong]

Hi, I like this pod, but it seems that I can not show CountriesViewController with my own viewController's navigationController. If I do that, your delegates won't work.

BTW: It might not a good idea to name a func start with a Capital letter.

Cheers, Andy
