      Description

      I don't find a way to implement selection from the end by index using SelectFS - maybe it is a bug or maybe it is not supported:

          String text = "Rot wood cheeses dew?";
          tokenBuilder.buildTokens(jCas, text);
      
          // uimaFIT: JCasUtil.selectByIndex(jCas, Token.class, -1).getCoveredText()
          assertEquals("dew?", jCas.select(Token.class).backwards().get(0).getCoveredText());
      

      The `uimaFIT` line is how it works in uimaFIT. Below my attempt in doing it using SelectFS. my understanding is that `backwards()` should change the iteration order (so starting at the end of the index instead of at the beginning in this case) and then `get(0)` should get the final token `dew?`. But instead, the statement returns the first token `Rot`.
