Grade should be up to date right now
	There are a couple wrong file uploads, etc. that I need to re-grade

Why trees?
	Pretty well covered in videos, but basically, search time

Let's make a quick and easy tree
	Don't let yourself not understand
	This is the simple overview
	No templates, classes, etc
	We'll do a set-style tree

Data has to support these operators:
	<
	==
	=
	<<

If not, it doesn't get to be in the tree
	string, int, float, etc. are fine
	Complicated types might need a couple operators defined
	C-style solution would be to include a comparison function
		Like qsort (remember this from the video?)

add, find, preorder traversal so we can draw it

Verify function carefully
	We'll use the debugger to do this
	Has anybody set up the debugger in VS code?
	I've seen people use it in regular Visual Studio

Don't leave too little time for the AVL tree
