`fill_h_apply_buffer <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f#L6>`_
  Fill the H_apply buffer with determiants for CISD

`h_apply_cisd <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f#L43>`_
  Calls H_apply on the HF determinant and selects all connected single and double
  excitations (of the same symmetry).

`cisd_sc2 <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/SC2.irp.f#L1>`_
  CISD+SC2 method              :: take off all the disconnected terms of a CISD (selected or not)
  .br
  dets_in : bitmasks corresponding to determinants
  .br
  u_in : guess coefficients on the various states. Overwritten
  on exit
  .br
  dim_in : leftmost dimension of u_in
  .br
  sze : Number of determinants
  .br
  N_st : Number of eigenstates
