Part $3$: Implement list.cpp

You will be implementing the List class from list.h$$it uses the linked list data structure

to build a list of Point$2$Ds $($which for all intents and purposes you can pretend are

ints$).$ The comments in list.cpp should guide you through the process.

You can test that your implementation is correct by running make linkedListTests

and running the resulting linkedListTests program.

Part $4$: Play snake with the fruits of your labor

This part is also optional, but fun!

After you get your List class working and passing all the tests, you can play the snake

game that I implemented in snake.cpp$.$ Compile with make snake. The game uses a

List to keep track of where all the pieces of the snake$$s body are. My code isn$$t the

cleanest, but I$$d be happy to explain it to you in office hours if you$$d like!

It$$s technically not a complete game, since the snake is allowed move on top of itself,

etc.$$can you fix that?
