    -added sub "add_data" for non-deleting loads; all calls to load unload
    -all carps now croak
    -nonparam flag for ensuring Friedman test appropriately "dump"-ed
    -cleaned-up ranking operation in Friedman test to handle ties - thanks to Gene Boggs' Statistics-RankCorrelation
    -added F-equivalent output option for Friedman test - thanks to "R" docs
    -cleaned-up POD and dist, with example file
    -removed bung sub fmax for now

    -generalised grand_total calculation within anova_indep which was appropriate only if equal number of observations per group: thanks to Cathal Seoghie for feedback that led to identifying this limitation
    -handling "missing values": added checking and purging of elements that are undefined or NaN before loading; this also reduces the later checks and possible croaks
    -added sub "table" for returning/printing a table of dfs, sums-squares, etc.; pretty formatting still needed ...

	-further work on appropriate handling of missing values and NaNs.
