New feature Query-Validator tools

I think many mobile developers are expecting query results like sqlite.
So, I made query validator module.

# How to works

1. Load test datas
2. Initialization
	- sqlite ( create tables, insert entities )
	- backend API ( create entities )
3. Query(sqlite, api)

# Running
```bash
$ mvn clean test

QueryValidationTest.sexEqualAndAgeGreaterthanequalOrSexEqual_sortNameDesc:269
