    We should have a plan verification test to make sure that this change actually has the
desired effect. This should be able to execute fine without your change as well, but the plan
will have and unnecessary SelectionVectorRemover in it today. You can see examples of plan
verification tests in /Users/jaltekruse/drill/exec/java-exec/src/test/java/org/apache/drill/TestCTASPartitionFilter.java
and other subclasses of PlanTestBase
