code: @Override
      public String getRandomValue() {
          StringBuilder buf = new StringBuilder();
          while (buf.length() < expectedSizeOfRandomValues) {
              int index = getIndexIntoWordArray();
              buf.append(words[index]);
              buf.append(" ");
          }
  
          return buf.toString().substring(0, expectedSizeOfRandomValues);
      }
docs: Return a sentence composed of a space separated sequence of fake words from the dictionary chopped so
  that the length is exactly equal to 'expectedSizeOfRandomValues'.
  <p>
  Despite the name, this value will NOT be random.
