================================================================
TOP OF LIST
* make a 2.3.2
- filter -x
- logireg w/ caveat
- stats2 hold-and-fit
- improved heterogeneity for sort,stats1,stats2,step,head,tail,top,sample,uniq,count-distinct
- implicit-csv-header feature
! join on partial value-field matches
MINOR: star-put fcn (for cheesy bar-charts) w/ min/max
