What this PR does / why we need it:
Literals and column refs are used by both the logical and physical plan. However, the interfaces they need to implement are partly private (
isValue()andisExpression()).Therefore they are wrapped in their own struct that implement these interfaces.
Special notes for your reviewer:
PR is based off
