Which issue does this PR close?
Part of #191
Rationale for this change
Demonstrate how to use DataFusion as a SQL query planner and optimizer in Python and then translate the logical plan to another execution engine.
The examples added in this PR run trivial SQL queries against Polars and Pandas.
To support a wider range of queries we would need to expose all of the DataFusion operators and expressions (see #191).
