Answer 1

If you can modify your HTML a little, you can come up with a general solution that will work with as many groups as you like (rather than just Country and Company).

HTML:

Company
Microsoft
Apple
Country
USA
UK

​JavaScript:

$(function(){
    $('.entityCheckboxHeader').click(function() {
        $('[name="'+this.name+'Sub"]').prop('checked', this.checked);
    });
});​

If you're not in a position to modify your HTML then the answer from Tats_innit is a nice, concise solution.
