Add grade notes to LMOD

Here's the way to export grade notes

1. Sort the spreadsheet so it has the same sort order as LMOD (aka alphabetical by last name)
2. open up lmod and then open up the javascript console
3. Scroll to the bottom of the assignment you want to grade so everyone loads
4. Create a javascript array in the console with all the grade notes as strings, call this array notes. This should be the same length as the number of students in the table!
5. Run the following snippets in order (each snippet may take a while to run - up to 20 seconds each)
