      Performs text lookups for localization.

      Assuming there is a instance of this class with a HTTP request set in your template's context named `l10n`, the VTL `$l10n.HELLO` would render to `hello` for English requests and `hola` in Spanish (depending on the value of the HTTP request's `Accept-Language` header).

      Parameters:
        `key` - The identifier for the localized text to retrieve.
      Returns:
        The localized text.

      Gets the current locale.
      Returns:
        The locale currently in use.

    - #### getBundleName

          protected String getBundleName(Object data)

      The return value of this method is used to set the name of the bundle used by this tool. Useful as a hook for using a different bundle than specified in your `LocalizationService` configuration.
      Parameters:
        `data` - The inputs passed from `init(Object)`. (ignored by this implementation).
      Returns:
        the name of the bundle to use
