showtbl(title, tbl, sort_type, limit, sort_order, posit,
w1, w2, gutter, f1, f2) displays tbl according to the arguments given.
The arguments are:
position name meaning default/alternative
1 title heading title ""
2 tbl table to be shown
3 sort_type type of sorting "ref"/"val"
4 limit lines of table output essentially infinite
5 sort_order increasing/decreasing "incr"/"decr"
6 posit first column "val"/"ref"
7 w1 width of 1st column 10
8 w2 width of 2nd column 10
9 gutter width between columns 3
10 f1 function of 1st column left
11 f2 function of 2nd column right
showtbl() returns a record with the first element being a count of
the size of the table and the second element the number of lines
written.

This procedure just grew. It needs rewriting.
And it has far too many arguments.

Deficiencies: Several features are not yet implemented. sort_order
and posit have no effect. In the case of sort_type
"val", the sorting order is decreasing.
