Small typo.

Hi fellow GSL'ers,

I found out that there is a small typo in the documentation for the
sorting functions:

An example has the following two lines:

  (...)
  gsl_sort_vector_index (perm, v);
  gsl_permutation_invert (rank, perm);
  (...)

which should be changed to:

  (...)
  gsl_sort_vector_index (perm, v);
  gsl_permutation_inverse (rank, perm);
  (...)

There is no function gsl_permutation_invert in any *.h file, and the
gsl_permutation_inverse function matches the previous prototype, and seems
to do what 'invert' was supposed to do in the example.

Greetings,
Alan
