Extending summary table functions to any defined function (e.g. mode, kurt, skew, etc.)

[FN]

The summary table is a handy operation that unfortunately lacks some basic statistics.

For instance, obtaining the mode is not possible even though that function exists in JMP.

See this: Additional functions for summary table via JSL 

In 2016, Brady Brady released an extended version that trims extreme values as well.  

Other functions to add can be first skew, kurt, corr, cummax, cummin, cumprod, cumsum, diff, first
value, last value, fitness to distributions, etc.
