description:
Use SLEPc to compute eigenvalues/vectors.

SLEPc offers a range of different algorirthms. The DOLFIN interface is similar ot that of KrylovSolver,


  Matrix A;

  // Create solver
  EigenvalueSolver esolver;

  // Solve all eigenpairs
  esolver.solve(A);

  // Solve 10 largest eigenpairs)
  esolver.solve(A, 10);

  // Get ith eigenpair
  esolver.getEigenpair(real xr, real xc, Vector r, Vector c, int i);

description:
Add test for SLEPc to configure.ac

SLEPc is a PETSc extension for computing eigenvalues and eigenvators. It has an interface which is consistent with PETSc and works with the PETSc data structures(matrices, vectors, etc). You can find it at http://www.grycap.upv.es/slepc/.

The actual implementation will follow shortly.
