Checks if SU functionality is available. Note that THIS WILL OPEN A SU PERMISSION POPUP.

root.isAvailable(function(res) {
    if(res)
        console.log("SU access is available and granted");
    else
        console.log("SU access was denied or is not available");
}, function() {
    console.error('An error occoured while checking for SU availability');
});

Executes the given command as root.
Please note that the fail callback will not always be executed.
You should manually verify that the command you issued actually worked.

root.run('whoami', function(res) {
    console.log(res); //['root']
}, function() {
    console.error('An error occoured while executing the command.');
});
