HW4, what points were taken off for.

4 points for each of the 3 main tasks.

Note: not taking off for yet - style, efficiency.  Make 
your code as simple and easy to understand as you can.
You should proofread it and go through drafts just like with 
a paper.  First you get it working, then you look back at it 
and see if you need to make any changes to make it simpler and 
easier to understand/modify in the fiture.

If the program does not run at all, it is a 0.  You can fix it and 
turn it in again to get back half of the points.

Remember the assignment is out of 12 points.

-1 no name.
-1 no collaborators listed.

-.5 for each missing formula for area.
-.5 if using hard-coded value instead of math.pi
-.5 if error or incorrect when invalid choice for shape.

-1 Code not correctly in function.
-2 no loop in favoriteSchool

-.5 letterGrade does not take care of all cases (e.g., 89.99999)
-1 did not do all the letters.
-2.5 does something, but not really close.
