Use "Simple LOBPCG" with Epetra test problem (computed here).

Use "Simple LOBPCG" with Epetra test problem (computed here).This example computes the eigenvalues of largest magnitude of an eigenvalue problem $A x = \lambda x$, using Anasazi's "simple" implementation of the LOBPCG method, with Epetra linear algebra. It constructs the test problem within the example itself.
