RelBuilderFactory (Apache Calcite API)

```
public interface RelBuilderFactory
```
A partially-created RelBuilder.
Add a cluster, and optionally a schema, when you want to create a builder.
A ProtoRelBuilder can be shared among queries, and thus can be inside a RelOptRule. It is a nice way to encapsulate the policy that this particular rule instance should create DrillFilter and DrillProject versus HiveFilter and HiveProject.
