Programming Assignment 1 Grading:
--------------------------------------------------------------------------------

First, create a grading directory (e.g., in your private CS directory) and
copy the testOne script to your grading directory.
You may need to run the command: chmod a+x testOne
to make it executable.

For each student:
1) Create a subdirectory for that student within your grading directory, e.g.,
       mkdir Student_Annie
2) Download the student's submission from the Learn@UW Program 1 dropbox into
   the student subdirectory
3) Go into the subdirectory and unzip the file
       cd Student_Annie
       unzip Program*.zip
4) If the student has any classes in addition to CustomerDatabase.java and
   InteractiveDBTester.java, you will need to rename these by hand.
5) From your grading directory, run the testOne script giving it the name of
   the student's subdirectory
       testOne Student_Annie

   This will do the following:
   - create subdirectories inside the student's subdirectory
     JAVA/ - containing appropriately renamed CustomerDatabase and 
	         InteraactiveDBTester files from which to run the tests
	 ERR/  - containing the output of diff'ing student results from expected
	         results
   - compile and run tests, displaying some info about compiling to the
     console and saving results from running tests to files
   - the CustomerDatabaseTester is used to test the student's CustomerDatabase
     class
   - the student's program is tested using the files below (if the student's
     InteractiveDBTester doesn't compile, the script tests it with the
	 solution InteractiveDBTester)
   - the student's InteractiveDBTester is tested with our CustomerDatabase
     (which can help identify inappropriate interactions between the two)
     Only input3 is tested here.

Test files and user input
input1.txt   - input file of 5 customers, 5 products, no tie for most popular
   sf1.txt   - tests search and find (as well as i)
   d1.txt    - tests discontinue (followed by s, f, and i)
   r1.txt    - tests remove (followed by s, f, and i)
   case1.txt - tests case insensitivity with s, f, d, and r
input2.txt   - input file of 10 customers, 6 products, ties for most popular
   i2.txt    - tests i, removing 5 most popular products followed by i
input3.txt   - sample input provided to students
   user3.txt - user input for sample 

6) Look through the ERR subdirectory to see how the student's output differs
   from our input

7) Make sure to look at the student's code as well (for style and
   documentation, among other reasons).


Comments to add to student's gradesheet (as an overall comment):
  Good job!

Note: for each top-level part (like CustomerDatabase class) that a student gets 
completely correct, make sure to add the comment:
  Good job!
so the student's gradefile contains some feedback for that part

Overall Comments:
  <b>Warning:</b> please try to correct the compiler warnings in the future
  <b>Warning:</b> you should not throw the errors after catching them in this case
