  * CommandHandler for the MKD command. Handler logic:

  * <ol>

  * <li>If the user has not logged in, then reply with 530</li>

  * <li>If the required pathname parameter is missing, then reply with 501</li>

  * <li>If the parent directory of the specified pathname does not exist, then reply with 550</li>

  * <li>If the pathname parameter specifies an existing file or directory, or if the create directory fails, then reply with 550</li>

  * <li>If the current user does not have write and execute access to the parent directory, then reply with 550</li>

  * <li>Otherwise, reply with 257</li>

  * </ol>

  * The supplied pathname may be absolute or relative to the current directory.
