docs: Creates a new Split for direct use without {@link Stopwatch} ("anonymous split") based on specified {@link SimonClock}.
  Stop will not update any Stopwatch, value can be added to any chosen Stopwatch using
  {@link Stopwatch#addSplit(Split)} - even in conjunction with {@link #stop()} like this:
  <p/>
  <pre>Split split = Split.start();
  ...
  stopwatch.addSplit(split.stop());</pre>
  <p/>
  If the split is not needed afterwards (subject to garbage collection) calling {@link #stop()} is not necessary:
  <p/>
  <pre>Split split = Split.start();
  ...
  stopwatch.addSplit(split);</pre>
  <p/>
  No callbacks are called for this Split.
