1) CFU_load : too new arguments leadtimemin and leadtimemax which allows to select a range of leadtimes. 

2) CFU_trend : It now outputs both the trend as before but also the linearly detrended data. So that the output come under the form of a list : $trend, $detrended. By linearly detrended data, I mean that the ensemble-mean trend is removed from each member.

3) CFU_consist_trend : If you provide the observational and model matrix, the trend and detrended data will be computed using only the common period (same idea as in the per-pair computation of anomalies).
