[boost] time_series and accumulators integration

It struck me that the boost::circular_buffer might work
great as an underlying container in the accumulators library;
which then could be used as the basis for many of the
smoothing functions that could be created in the time_series
library, similar to the "simple_moving_average" functor that we
just created.

In addition, the accumulator::tag could be sent in as a template
parameter to the time_series functors,
eliminating the need to have a functor for each of the
accumulator statistical algorithms.

Example might be:

template <typename Accumulator>
struct generic_smoothing_functor
{
      Accumulator accumulator;

      out operator()(Type in, offset start, offset end)
      {
               accumulator(in);

      }
};
