Check that the time evolution of a given parameter is consistent with its past evolution.
Compare sum of differences between snow depth (HS) value and HS value before and HS value afterwards, respectively, with 4 times of the standard deviation of HS in a defined time period (something like MAD) First, the standard deviation of HS is calculated for a certain time period. Afterwards, the difference between the value and the value before and the difference between the value and the following value are calculated. Then, the sum of the two differences is calculated and compared with 4 times of the standard deviation. Is the sum lower than the standard deviation, the HS value is accepted. Otherwise the HS value gets invalid.

It takes as arguments the window parameters as defined in WindowedFilter::setWindowFParams().

| A function that computes the start and end for a window for the 'index' element from ivec The principle is to compute the first index that matches the minimum number of points criteria, and the one that matches the minimum time window, then combine them (with the equivalent of OR: we take the MIN index). Afterward, we compute the last index [...] for number of points and the last index [...] for the time window and combine them (with the equivalent of OR: we take the MIN index) or vice versa for right centering.
