One box time series and twa values

- one_box() creates decline time series from mkinfit objects or simply
  from a half-life
- sawtooth() generates sawtooth curves for arbitrary application
  patterns and decline models
- twa() calculates moving window averages
- max_twa() gives their maxima and
- plot.one_box() can plot series generated by one_box() or sawtooth(),
  optionally adding a greay rectangle to illustrate the maximum moving
  window time weighted average
