plMergeOpts: Reset internal option table info structure.

plResetOpts ();

Resets the internal command line options table to the default builtin value. Any user options added with plMergeOpts will be cleared. See plparseopts for details of how to parse these options in a program.

This function is currently available in C, C++, Java, Ocaml and Octave, although it is not much use in Java or Octave since they don't have plMergeOpts.

This function is not used in any examples.
