Refine and add terms relevant to zero-shot and few-shot learning

[caufieldjh]

AIO currently includes two terms involving few-shot learning:

• AIO:GeneralizedFewshotLearning
• AIO:IncremenetalFewshotLearning

and two terms for zero-shot learning:

• AIO:ZeroshotLearning
• AIO:ZeroShotLearningLLM

These are all children of AIO:DeepNeuralNetwork. I don't think that makes sense - zero-shot and few-shot learning are general strategies, not types of networks, so perhaps they'd be appropriate as children of AIO:TransferLearning.
"They" being AIO:ZeroshotLearning and a to-be-created AIO:FewShotLearning.
