> This patch adds AlgebraVisitor that visits the relational operators of the
> algebra expressions recursively. It is helpful for implementing unit tests
> and utility methods related to algebra expressions.
> In addition, this patch refactors LogicalPlanner class to be based on
> AlgebraVisitor. This change improves the code readability.
