auto_check

This program works on all http://boston.lti.cs.cmu.edu/classes/11-642/HW/HW*/Testing.html pages.

First you need to load it as an unpacked extension in Google Chrome. Then on the test service pages, clicking on the YueSeHan-PangMaiLang icon will trigger one of the two events below:

• If only 1 checkbox is checked, the next 9 checkboxes will also be checked.
• If any other numbers of checkboxes are checked, all checks will be cleared.
