> The current Tajo does not have any verification system to check whether a
> logical plan is valid, or not. LogicalPlanVerifier will verify the followings
> of a logical plan:
> * operand types checking
> ** some operators have type restrictions. For example, plus(\+)'s operands
> must be numerical values.
> * Table and column existence check.
> ** Examples are as follows:
> *** a create table statement must check if the table already exists
> *** columns included in select list must exist in corresponding tables.
