      Improvements needed for production level code:

      1) Sparse Matrix Algebra.
      Intel or Eigen Libraries
      2) Lanczos or Davidson iterative power method to find the ground-state
      of superblock.
      E. Dagotto, Rev. Mod
      Phys. 66, 763 (1994)
      3) Hlvs multiplication “onFly” without creating the Hamitonian of the
      superblock.
      4) Wave-function transformation (Prediction)
      to approximate the ground-state
      of next DMRG step.
      S. R. White, Phys. Rev.
      Lett. 77, 3633 (1996)
      5) Use Symmetries of the Hamiltonian.
      translation invariance
      6) Parallelization using multiple cores (OpenMP, pthreads), or using
      multiple nodes (OpenMPl) or both.
