I don't see how naming the parameter "undefined" would help, since 0 should be
a valid interger option. Except from that, I follow.

I have made some improvements to the SLEPc eigenvalue solver, making it
possible to set tolerance and max iter from dolfin. Another thing we should
consider is making it possible to specify the problem type, EPS_HEP, EPS_NHEP,
EPS_GHEP, or EPS_GNHEP (or so).
