/**
 * @fileoverview `ConfigDependency` class.
 *
 * `ConfigDependency` class expresses a loaded parser or plugin.
 *
 * If the parser or plugin was loaded successfully, it has `definition` property
 * and `filePath` property. Otherwise, it has `error` property.
 *
 * When `JSON.stringify()` converted a `ConfigDependency` object to a JSON, it
 * omits `definition` property.
 *
 * `ConfigArrayFactory` creates `ConfigDependency` objects when it loads parsers
 * or plugins.
