Adding secret number homework

Adding homework
This if logic definitely works. To make it a little more clear to other developers, you might want to combine the code on lines 54-57 with the code on lines 59-63. You can do this by saying:
```ruby
if guess == secret 
   puts "Congratulations your guess of #{guess} is correct."
   break
 elseif guess > secret 
   puts "Sorry your guess was too high"
elsif guess < secret 
  puts "Sorry your guess was too low"
end
```
