  @brief Driver for the ladder-diagram calculation: the Ladder{} input block.
  @details
  Calculates (and iterates to convergence) the ladder integrals Lk, writing
  them to the .lk file. Then constructs the ladder correlation potential,
  Sigma_L, for each valence state, and writes these to the .sl file.
  The .sl file may then be read in by the Correlations block (ladder_file
  option) to include Sigma_L into the correlation potential.
  Runs before Correlations. Options are parsed from the Ladder{} input block.
