arc1.rs

[jhiver]

Hello Rustaceans, first of all thanks for this fantastic project, it's been helping me so far.

I have an issue with arc1.rs though.. I was doing the exercices humming along nicely and all of the sudden BOOOOM all at once we have threads, closures, Arc, and join handles. And for the life of me I don't even know out what this code is supposed to achieve!

Would be nice to explain what we're trying to do here, and maybe introduce some other concepts (closures, threads) through exercices prior to this one.

Thanks for your time and your help making the rust learning curve smoother! Have a great day
