Usage

Execute A Query

    std::shared_ptr<PGeneralEvaluation> ge = std::make_shared<PGeneralEvaluation>( ... );
    ge->ParseCypherQuery(query);
    ge->GenerateLogicalPlan();
    ge->DoQuery();
    ge->temp_result_->print();

Generate Plan Tree For A Query

    PCypherParser parser;
    std::unique_ptr<CypherAST> ast;
    std::unique_ptr<PTreeNode> plan;.
    ast.reset( parser.CypherParse(query, param, nullptr));
    plan.reset(PQueryTree::GenerateQueryTree(ast.get()));
    plan->print();
