Decided not to make a Queue
-Created LinkedList

-Changed the name of Stack to ArrayStack (in preparation of creating a
trait called Stack, so that I can make a LinkedListStack)
Whoops.
Properly represented Stack as an abstract Data Type, by making it an
abstract trait instead of just an implementation as an array
Get methods
Somewhat refactored a find method
Testing out shiny new LinkedListStack
Gah. Forgot this. #versioncontrolproblems
