just a tiny libary based on jsonschema libary that allows you to test if your object is valid and if so to combine it with your deafults data

### usage example

### lazy 

```js

const validate = require('djsv');

// create your schema

const json = {

    "type": "object",

    "properties": {

        "id": {

            "type": "string",

            "default": "id",

            "required": true

        },

        "age": {

            "default": 30,

            "type": "integer"

        }

    }

}

 let validObject = validate(json,{id:"maty"}) // validObject.instance => {id:"maty",age:30}

 let validObject = validate(json,{id:"maty",age:20}) // validObject.instance => {id:"maty",age:20}

 let validObject = validate(json,{age:20}) //=> {id:"maty",age:20} => error:{valid:false, errorDescription:"id is required"}

 let validObject = validate(json,{id:123456}) //=> error:{valid:false, errorDescription:"id is not a string error "}

```

### with schema initiation before

```js

let validateWithSchema = validate(json);

let obj= { id: "12345", info: { age: 6 } };

console.log(JSON.stringify(validateWithSchema(obj).instance));

```

### ignore null option

ignorenull option allows you to set the default param in the return object although the value is defiend 

```js 

validateWithSchema = validate(json);

console.log(JSON.stringify(validateWithSchema({ id: "12345", info: { age: 6, familyName: null } }).instance)) //=> {"id":"12345","info":{"age":6,"familyName":null}}

console.log(JSON.stringify(validateWithSchema({ id: "12345", info: { age: 6, familyName: null } }, { ignoreNull:true }).instance)) //=>{"id":"12345","info":{"age":6,"familyName":"unknown"}}

```
