Feature enhancement request: Allow serialization of the Graphmaster object

[ShadowEO]

I'm attempting to build a bot out of your code and would love to be able to serialize the graphmaster so that I don't have to load the entire AIML folder again from scratch. I attempted to look into making the classes serializable but I can't seem to manage it.

Any hints on what needs to be done to accomplish this, or am I stuck loading AIML from files every time I want to start the bot code up?
