Submitting all of my homework and midterm!

To perist this data into an array, you could push each tweet into an instance variable that is an array. Kind of like:
'@instance_array << tweet'
or another option is to use the `.map` method instead of `.each`. 
`.map` iterates over an array the same way `.each` does but it returns a collection. See http://www.ruby-doc.org/core-2.1.2/Array.html#method-i-map
