This rule enforces that file name of classes decorated with @Directive must have suffix "directive" (or custom) in their name.

## Rule Details

This rule follows the recommendation from the [Angular styleguide](https://angular.io/guide/styleguide#style-02-03).

    {
      "suffixes": ["directive", "validator", "directive.mock"]
    }
  ]
}
```
