> Make {{RelBuilder}} configurable, so that particular optimizations can easily be turned off.
> I propose to add a class {{RelBuilder.Config}}, which is immutable and has a public final field for each configuration property; also a class {{RelBuilder.ConfigBuilder}} to create a config.
> {{RelBuilder.create(FrameworkConfig frameworkConfig)}} will get a config by calling {{frameworkConfig.getContext().unwrap(RelBuilder.Config.class)}}.
