The idea is to pick items at random from a set.

   Once an item has been picked it should have a chance to be picked
again but a little bit less likely.

   I am not sure how to best do this but I have a simple example here
to demonstrate what I mean.



   a=.i.10
   b=.10#10
   c=.b#a
   d=.+/b
   e=.?d
   f=.e{c
   SEL_sel_=.i.0
   SEL_sel_=.SEL_sel_,f
   b=.b- f=a
   c=.b#a
   d=.+/b
   e=.?d
   f=.e{c
   SEL_sel_=.SEL_sel_,f
   b=.b- f=a
   c=.b#a
   d=.+/b
   e=.?d
   f=.e{c
  SEL_sel_=.SEL_sel_,f
   b=.b- f=a
   c=.b#a
   d=.+/b
   e=.?d
   f=.e{c
  SEL_sel_=.SEL_sel_,f
  SEL_sel_
  b

SEL_sel_ collects all the picked items
b gives how many of each items are of each
