    * Provides a wrapper for translation, using the global 'gettext'
    * function if it is present.  Provides a method that
    * simply returns the input if the expected global 'gettext' is
    * not provided.
    *
    * Ideally once gettext is no longer needed on a global scope,
    * the global ref can be deleted here.  For now that is not possible.
    * Also, if future alternate means were provided, we could put that
    * logic here.
    *
    * This could also be done in the context of the filter, but
    * the approach taken here was to separate business logic
    * (translation) from filters, which are arguably more
    * presentation-oriented.
