I put together this early draft version of of 'gev' for calculating
generalized eigenvalues.  I have never interfaced Fortran with Octave
before, so I'd appreciate any tips on how to improve it.

I hope that, once the function works sufficiently well, it can be
integrated into 'eig'.

Regards
Stéfan
