DESCRIPTION
randtable outputs n random rows from its input table (or tables).
If the optional parameter n is not given rand outputs all
of the input rows in a random order.

NOTES
randtable is implimented by stripping off the table header and calling
rand. rand itself is implimented in awk and may be of questionable
use for large input files.
