/**
 * @name ExtError
 * @summary Extension to the basic JS Error.
 * @description
 * The built-in JavaScript Error class is extended by adding a code to allow for Error categorization. In addition to the normal `stack`, `message`, the numeric `code` and `data` (any types) parameters are available on the object.
 * @example
 * <BR>
 *
 * ```javascript
 * const { ExtError } from '@tetcoin/util');
 *
 * throw new ExtError('some message', ExtError.CODES.METHOD_NOT_FOUND); // => error.code = -32601
 * ```
