1. Add fix for twopirllc#742 …

   Add sum_signed_rolling_deltas function and proper NumPy vectorization.
   Some TMO indicators in TV consider the rolling window to be exclusive
   of the current day, while others consider it inclusive. Since this
   series is used to compute the moving averages and momentums for the
   TMO, there would be a plot mismatch against TV unless we dealt with
   both cases.
   Added doctests for both cases, noting that since the series must be cast
   to float type, fp precision representation issues might arise, which
   makes the Pandas Series equality tests unsuitable. We use np.allclose so
   that we can deal with both the fp precision issues if they arise, and
   with the necessary NaN padding as well.
