> {{EvaluatorRequestor}} and {{EvaluatorRequest.newBuilder()}} are almost always used together in a pattern that looks like this:
> {code}
> requestor.submit(EvaluatorRequest.newBuilder()
>   .setNumber(1)
>   .setMemory(64)
>   .setNumberOfCores(1)
>   .build());
> {code}
> It would be good to have a nicer, more fluid API here:
> {code}
> requestor.newRequest()
>   .setNumber(1)
>   .setMemory(64)
>   .setNumberOfCores(1)
>   .submit();
> {code}
> This could be done by creating a subclass of {{EvaluatorRequest.Builder}} which has a reference to the {{EvaluatorRequestor}} instance and implements {{.submit()}} as:
> {code}
> void submit(){
>   this.requestor.submit(this.build());
> }
> {code}
