code: protected List<Vertex> toVertexList(List<Term> wordList, boolean appendStart)
      {
          ArrayList<Vertex> vertexList = new ArrayList<Vertex>(wordList.size() + 2);
          if (appendStart) vertexList.add(Vertex.newB());
          for (Term word : wordList)
          {
              CoreDictionary.Attribute attribute = guessAttribute(word);
              Vertex vertex = new Vertex(word.word, attribute);
              vertexList.add(vertex);
          }
          if (appendStart) vertexList.add(Vertex.newE());
          return vertexList;
      }
docs: 将中间结果转换为词网顶点,
  这样就可以利用基于Vertex开发的功能, 如词性标注、NER等
  @param wordList
  @param appendStart
  @return
