-function FLAG = flag_implicit_skip_nan(i)
-% FLAG_IMPLICIT_SKIP_NAN sets and gets default mode for handling NaNs
-%	1 skips NaN's (the default mode if no mode is set)
-% 	0 NaNs are propagated; input NaN's give NaN's at the output
-% 
-% FLAG = flag_implicit_skip_nan()
-% 	gets current mode
-%
-% flag_implicit_skip_nan(FLAG)
    % sets mode 
-%
-% prevFLAG = flag_implicit_skip_nan(nextFLAG)
-%	gets previous set FLAG and sets FLAG for the future
-% flag_implicit_skip_nan(prevFLAG)
-%	resets FLAG to previous mode
-%
-% It is used in: 
-%	SUMSKIPNAN, MEDIAN, QUANTILES, TRIMEAN
-% and affects many other functions like: 
-%	CENTER, KURTOSIS, MAD, MEAN, MOMENT, RMS, SEM, SKEWNESS, 
-%	STATISTIC, STD, VAR, ZSCORE etc. 
-%
-% The mode is stored in the global variable FLAG_implicit_skip_nan
-% It is recommended to use flag_implicit_skip_nan(1) as default and 
-% flag_implicit_skip_nan(0) should be used for exceptional cases only.
