It may be more clear to have MAX | MIN function for Numbers and a set of
SORTED functions for Strings.
> Add MAX & MIN Stellar functions

> Key: METRON-1286
> URL: https://issues.apache.org/jira/browse/METRON-1286
> Project: Metron
> Issue Type: Improvement
> Affects Versions: 0.4.1
> Reporter: Jasper Knulst
> Priority: Minor
> Labels: features
> Fix For: 0.4.2
>
>
> Currently Stellar lacks straightforward MAX & MIN functions that take just a
> list of values as input.
> The functions STATS_MAX and STATS_MIN only take the internal Stellar
> statistics object as input.
> Having MAX and MIN will be easier and understandable to most
