Changes:
  * BeginStory/EndStory are now nil/Close() to be more in line with
    the way that other go libraries work for this sort of thing.
  * Print* statements are now correctly interleaved with Assertions
    and Scopes and such in reporting.
    * So I removed the print-to-terminal functionality... it now all
      goes through reporting.
    * Removes 'dishonest' behavior of the story reporter :)
  * New nestedReporter correctly aggregates execution of scopes and
    consolidates their relative nesting-ness.
    * Uses new NestedScopeResult struct internally... it serializes
      to JSON directly pretty well, too.
  * Revamped Printer to have tighter control over the display (much
    harder to get it's state looking bad now.)

…und the loop.

This fixed an intermittent failure that was only exposed when the map iteration put the "0" key after either the "1" or "15" keys.
