Added support for run() and created function for terminal errors

Sorry if I'm being naive here, but what's the purpose of run? @cwbeck

__destruct() causes errors not to be thrown properly. This allows it to be called directly so errors can be caught. It's a PHP issue.

-1 use parse.

Your try block should not be around the definition of the options. Errors will be thrown when the tokens are parsed. This happens when you access an option key for the first time.

$cmd->option('c');

try {
    $cmd['c']; // calls $cmd->parse()
} catch(Exception $e) {
    ...
}

The \ were just removed for phpdoc compatibility. Don't see any reason to bring them back.

The run is unnecessary. It is a clone of the parseIfNotParsed method. parse and isParsed are both public, so this can be handled in user code if desired.

I like the createTerminalError method addition.
