> Calcite has a TableFunctionScan, which is a RelNode, takes a function, 0 or more RelNode inputs, and 0 or more other arguments.
> RelBuilder does not support TableFunctionScan yet.
> add In RelBuilder TableFunctionScanFactory which will create LogicalTableFunctionScan like as for LogicalTableScan and factory for others RelNodes [ [example|https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/tools/RelBuilder.java#L125] ]
> also adding a functionScan method, analogous to the scan method but for table functions.
