5.  def canEvaluate(expr: Expression, plan: LogicalPlan): Boolean

   Returns true if expr can be evaluated using only the output of plan.

   Returns true if expr can be evaluated using only the output of plan. This method can be used to determine when it is acceptable to move expression evaluation within a query plan.

   For example consider a join between two relations R(a, b) and S(c, d).

   - canEvaluate(EqualTo(a,b), R) returns true - canEvaluate(EqualTo(a,c), R) returns false - canEvaluate(Literal(1), R) returns true as literals CAN be evaluated on any plan

11.  def findExpressionAndTrackLineageDown(exp: Expression, plan: LogicalPlan): Option[(Expression, LogicalPlan)]

    Find the origin of where the input references of expression exp were scanned in the tree of plan, and if they originate from a single leaf node.

    Find the origin of where the input references of expression exp were scanned in the tree of plan, and if they originate from a single leaf node. Returns optional tuple with Expression, undoing any projections and aliasing that has been done along the way from plan to origin, and the origin LeafNode plan from which all the exp

    Flatten all inner joins, which are next to each other. Return a list of logical plans to be joined with a boolean for each plan indicating if it was involved in an explicit cross join. Also returns the entire list of join conditions for the left-deep tree.
