Error3 is proper JS error implementation. It supports error codes, message formatting (e.g. i18n) and nested errors.

# CHANGELOG

### 3.0.0

* Removed code creation from constructor name.
* Add class field `Error3#code` as part of error interface:
  ```javascript
  class MyError extends Error3 {
    code = 'my_error'
    format() {
      return 'Ooops'
    }
  }
  ```

### 2.0.0

* Error3 rewriten to TypeScript.
* No static message generation methods. Custom constructors with `format` method are using now:
  ```javascript
  class MyError extends Error3 {
    format(details) {
      return 'Custom error message based on ' + details.property
    }
  }
  ```
* Interface simplified. Now library errors file could look like so:
  ```javascript
  export default class MyErrGroup extends Error3 {}

  export class MyParticularError1 extends MyErrGroup { /* error implementation */ }
  export class MyParticularError2 extends MyErrGroup { /* error implementation */ }
  // etc...
  ```
* No more manual message creation. All errors should be specified and has it's own class.

### 1.7.0

* Add errors to code stringification method:
  ```javascript
  Error3.CODE = function(details, errors) {
      //...
  };
  ```
* Update positional arguments handling. Now wrong arguments will throw.
* Add `toString` method to provide code into error string:
  ```javascript
  String(new Error3('not_found', 'Nothing found'));
  // > "Error3: [#not_found] Nothing found"
  ```
* Fix static method `from` to prevent of using deprecated method `fromJSON`.
* Enhance documentation.
