Description: Average grade calculator.
Average is calculated automatically when input is received,
however it can be also calculated using button elow the table;
If assignment is unsubmitted - change color cell to yellow;
If average<40% - change cell color to red;
If any non-digit character is entered in editable cells - disregards input;
The second table calculated information on the assignments due.
