Adding Teddit Conditionals and the framework for what will be my secret number game.

Had a study sesh this weekend with a Rubyist friend and spent more time on Teddit Conditionals so I could fully understand hashes vs. arrays better, began working on the secret number game, but will finish by Wednesday. 
another option for this  would be to pass a range to rand.
```ruby
rand(1..10)
```
