// When item is selected, the code will highlight the row this item is in. The code will also
// select/unselect all the checkboxes when top checkbox is clicked.

// Assumptions:
// 1. Code will not highlight rows in Netscape 4, but will select/unselect checkboxes with the 
//    click of the top checkbox.
// 2. The name of the top checkbox (the one that selects all other checkboxes) has to be
//    "chkAll" (no quotes).
