21 * CommandHandler for the STOU command. Handler logic:
22 * <ol>
23 * <li>If the user has not logged in, then reply with 530 and terminate</li>
24 * <li>Create a new file within the current directory with a unique name</li>
25 * <li>Send an initial reply of 150</li>
26 * <li>Read all available bytes from the data connection and write out to the unique file in the server file system</li>
27 * <li>If file write/store fails, then reply with 553 and terminate</li>
28 * <li>Send a final reply with 226, along with the new unique filename</li>
29 * </ol>
