The smoothing algorithms have been renammed as Process instead of Filter. The rate and the Tukey filters have been improved so that they correctly handles nodata.

A new resampling algorithm has been introduced: "none". It does just that: nothing. This is an easy way to debug filters by not performing any temporal interpolations.

The getMedian method has been re-implemented using the standard nth_element method for increased performances.

The doxygen documentation has been updated to reflect the latest changes.
