docs(ngRepeat): update step_02.ngdoc with challenge

[nicolaiskogheim]

I tried making a 5x5 table using two ng-repeaters. This showed me that it is the element with the ng-repeat attribute on it that gets repeated, and not only the contents of it. Next time I won't be adding the repeater to the table tag :)
Anyway, this is why I propose to add a little challenge to the readers regarding ng-repeat.

I see now that I missed some of the guidelines regarding commit messages. To save you the trouble, I'm just going to cancel this thing.

It's no big deal dude, it just takes a quick git commit --amend to fix the message :p I was just waiting to see what other people think about merging it, it's kind of a cute thing to add but not really informative on its own.

[nicolaiskogheim]

It was never my intention to add cuteness to your docs.

I think it adds more value to the ng-repeat example over. It's not clear in the example what gets repeated. It may be ok to just say "Note that the get's repeated, not the ", but where's the educational value in that?
I can understand that you might not share my view on this, but then again, you know a lot about angular, and I don't.

take it easy, I'm not saying it's not worth adding, I just wanted to wait for a second opinion =) I'll re-open. I actually like the addition, I'm not sure how that wasn't clear from my first comment :p

[nicolaiskogheim]

I'm sorry if I come of as upset or touchy. That's my poor english skills, not me :)

I'll amend the commit message now. Just in case

[btford]

I don't feel strongly about this either way.

[caitp]

I kind of like it, so if nobody has a serious issue with it I'll merge

[btford]

go for it

merg'd, thanks @nicolaiskogheim
