Well, your code seems to work okay.
What do you want to ask?

A couple of further guildelines from me before I wish you good wishes to your investigations:

• subscribe to "Inline" mailing list
• remove those use ConsistentSet ...; and no AutoLoader; and configure your system to find needed resources appropriately
  (as I did before running your code)
• be brave

Courage, the Cowardly Dog
