版本：

​ v0.0.2

使用方式

• go get github.com/WZFlik/neurodb-go-driver
• import "github.com/WZFlik/neurodb-go-driver/neurodb"
• 开始编码

   package main

import "github.com/WZFlik/neurodb-go-driver/neurodb"

func main() {
	db, err := neurodb.Open("127.0.0.1", 8839)
	if err != nil {
		panic(err)
	}
	resultSet, err := db.ExecuteQuery("match (n) return n")
	//traversal resultSet
	_ = resultSet
}

示例代码

	resultSet, err := db.ExecuteQuery("match (n) return n")
	if err != nil {
