Week 2 Homework

Hi Renee,

Homework for week 2.

Question about Git/GitHub.  When I created this pull request, it looks like in addition to the week 2 homework, it is including my week 1 homework files.  Is that normal?  I expected to just see it pushing my week 2 stuff, but then again I know that you did not "accept" the week 1 pull requests for the class, is that why those files are included in this pull request (as they are still newer compared to the original week 1 files in the main repository)?

Thanks

Scott
