Would you accept a PR that allowed more access to private vars HashMap in AbstractEvaluator?

Hi,

Thanks for this code. I would like to evaluate a series of statements then use the names/values in private HashMap vars to process the result.

The current code allows a get to the vars if the key name is known. It does not provide a method to get the vars keyset as far as I can tell.

Would you accept a PR that adds something like this to AbstractEvaluator?

public Set<String> getNames() {
        return vars.keySet();
}

Am I way off base? I didn't look at the implications of adding getNames() to interface Evaluator. Would that be better?

Thanks!
