Title: Just some minor changes. Totally untested.

Added a link to the actual crossfit games profile page.
Tweaked a few of the xpath iterations to use Ruby #collect method instead of #each and shoving into array. #collect and #map are synonyms. My general preference is when you are just grabbing one attribute from the items in the collection, I think of that as "collect," meaning... go and collect all these attributes. I would use map when I wan to more or less transform a collection into another collection. I think of it like go and map this collection to something else. But like I said, they both do the same thing.

`.collect(&:text)` is just shorthand for `.collect { |score| score.text }`
