//CAVEAT: This script does not up-vote a Friend comment when the Friend comment is
//an Author comment. This script relies on the Newsvine class attributes. For Newsvine,
//the Author class trumps the Friend class. There is no simple mechanism for determining
//whether or not an Author is also a Friend without loading an additional page. This
//will be an option in a future version of the script.
//Other issues:
//Need error-handling after vote to determine whether or not to 'check' toolsboxes.
//If multiple tabs are open, checkboxes can get out of sync.
