Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

I really need to learn RegEx
this is definitely a unique approach
that's called PascalCase iirc
I threw a a lookahead (?!^) in the regexp so that it only matches capitalized letters in the middle of the text (e.g., 'FooBar' -> 'Foo Bar', rather than ' Foo Bar').
I'm sort of surprised this wasn't one of the tests, but perhaps initial caps are not proper camelCase.
