Rename Evaluator to Predictor and .evaluate(...) to .predict(...) to avoid confusion.

[adivekar-utexas]

In recent years, "evaluation" has taken a specific meaning in the language of foundation models, more aligned with LMEval, LLM-as-a-Judge, etc. It no longer means to perform inference from a model.

There as also significant confusion because Evaluator.evaluate clashes with the Metric.evaluate(...) function. The latter usage is correct.

Given this, it makes sense to rename Evaluator subclasses to Predictor and the .evaluate(...) method to .predict(...).

Potential other names considered:

• InferenceManager: too long (annoying while using in notebook). "Manager" is a meaningless term here which does not convey the semantics.
• Inference: makes sense as a subclass (LocalInference, RayInference, etc) but not as
• Inferrer: technically correct but not a real word.

Aggreed, Predictor seems to be a better choice here
