Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public interface QueryEvaluationStep
A Step that may need to be executed in a EvaluationStrategy. The evaluate method should do the minimal work required to evaluate given the bindings. As much as possible should be pre-computed (e.g. resolving constant values)
