### Usage
#### NestedAccessor
```ts
const source = {
"data": {
"id": 1,
"name": "Countries classifier"
},
"countries": [{
"name": "Russia",
"cities": [{
"name": "Moscow",
"extra": {
"codes": [{
"value": 7495
},
{
"value": 7499
}
]
}
},
{

"extra": {
"codes": [{
"value": 375017
}]
}
}]
}
]
};
const accessor = new NestedAccessor(input);
console.log(accessor.get('data.name')); // 'Countries classifier'
console.log(accessor.get('countries.name')); // ['Russia', 'Belarus']
console.log(accessor.get('countries.cities.name')); // ['Moscow', 'Petersburg', 'Minsk']
console.log(accessor.get('countries.cities.extra.codes.value')); // [7495, 7499, 7812, 375017]
accessor.set('data.name', 'New name');
console.log(accessor.get('data.name')); // 'New name'
