The resampling has been deeply transformed in order to produce more consistent results. By doubling the data cut window, the resampling can now properly fill a 23 hours gap with a 24 hours window. The resampling now either fills the whole gap or do not fill anything (if the gap is too large). When activating "extrapolate", a gap is now filled by the sides instead of by the middle (which was producing weird results). The drawback is that the cut window had to be doubled, which is quite costly (going from 1 day to 10 days makes it 7.5 times slower, and going to 20 days makes it 15 times slower). However, this more logical and consistent behavior will allow the user to specify the window size that he needs instead of always picking something extremely large to be on the safe side. Finally, the resampling code has been cleaned up so that each algorithm is built along similar lines.
