Module 5 Grading Guideline

Note: If there is no file named PictureManipulator2.java submitted, 
award 0 points total for this assignment.

The testing of these submissions should be done by simply creating
an instance of the PictureManipulator2 in the Interactions pane and
then creating an instance of a Picture.  Pass the picture to the
appropriate methods and ensure results.

If the methods use the getPixels() method that returns an array and the 
students process the array and do not use the nested loop structure, then 
the student should earn no credit for the methods.
