[SCIP] Convert a set of tuples to table

this is in general a good idea for complicated data. But I would not use
Zimpl to generate the file but a nice scripting language like phython/awk/perl
whatever you like.  Then you can use the read statement to read the data into
a param or set.

Best regards,
Thorsten
