general ruby fixes

Hey Tell,
I checked through your Ruby, and here are my changes _to your Ruby code_. Most of it is just small changes, but check through it none the less. I tried to give you some information in the commits, but let me know if any of it doesn't make sense. Happy to talk through anything.

If you want to look through any of this on your computer, before merging or anything, move to the repository on your computer and then run the following:

**To get the repository:**
```sh
git checkout -b nquinlan-ruby-fixes master
git pull https://github.com/nquinlan/daily-flow.git master
```
**To play with the repository:**
```sh
gem install bundler # if you don't have it already
bundle install
bundle exec basic.rb
```

Overall, awesome project and good work!
