* @fileoverview The factory of `ConfigArray` objects.
*
* This class provides methods to create `ConfigArray` instance.
*
* - `create(configData, options)`
* Create a `ConfigArray` instance from a config data. This is to handle CLI
* options except `--config`.
* - `loadFile(filePath, options)`
* Create a `ConfigArray` instance from a config file. This is to handle
* `--config` option. If the file was not found, throws the following error:
* - If the filename was `*.js`, a `MODULE_NOT_FOUND` error.
* - If the filename was `package.json`, an IO error or an
* `ESLINT_CONFIG_FIELD_NOT_FOUND` error.
* - Otherwise, an IO error such as `ENOENT`.
* - `loadInDirectory(directoryPath, options)`
* Create a `ConfigArray` instance from a config file which is on a given
* directory. This tries to load `.eslintrc.*` or `package.json`. If not
* found, returns an empty `ConfigArray`.
* - `loadESLintIgnore(filePath)`
* Create a `ConfigArray` instance from a config file that is `.eslintignore`
* format. This is to handle `--ignore-path` option.
* - `loadDefaultESLintIgnore()`
* Create a `ConfigArray` instance from `.eslintignore` or `package.json` in
* the current working directory.
*
* `ConfigArrayFactory` class has the responsibility that loads configuration
* files, including loading `extends`, `parser`, and `plugins`. The created
* `ConfigArray` instance has the loaded `extends`, `parser`, and `plugins`.
*
* But this class doesn't handle cascading. `CascadingConfigArrayFactory` class
* handles cascading and hierarchy.
