  Log:
  After some experimenting and reading, I found out that the Jacobi-Davidson
  scheme would in fact be slower than the Arnoldi/Lanczos iteration
  eigensolver. So I changed the dummy interface to JDQZ by an interface
  to the ARPACK library.
  For now, only the real symmetric case is implemented. Of course the idea
  is to put the complex non-Hermitian case, since for the normal case
  the conjugate gradients seems to be faster.
