This code will probably be closely linked to the code for #19

Yep. They're highly related. I think this issue is prior to #19

Is it can be represented by "Load empty memory and experience"?

I think @ccrock4t 's saying is logically reasonable.

I was trying to split the problem into smaller ones. To load experience, one can choose whether to reset the system or just to accumulate the experience upon old one. When loading a "memory" file, maybe the system should be reset, but if not I don't know whether it could work.

Oh yes, maybe I'm assuming that the "load" contains "reset" - in this aspect, you're right.
Accumulating memory is a good and novel idea for me. I think the key is combining concepts in memory.

Maybe pull request #27 can have a try, or at least it allow you run and manage multiple reasoners without run several Python program.
