  TAOBQNKTR - Bounded Quasi-Newton-Krylov Trust Region method for nonlinear minimization with
              bound constraints. This method approximates the Hessian-vector product using a
              limited-memory quasi-Newton formula, and iteratively inverts the Hessian with a
              Krylov solver. The quasi-Newton matrix and its settings can be accessed via the
              prefix `-tao_bqnk_`

  Options Database Keys:
  + -tao_bqnk_max_cg_its - maximum number of bounded conjugate-gradient iterations taken in each Newton loop
  . -tao_bqnk_init_type - trust radius initialization method ("constant", "direction", "interpolation")
  . -tao_bqnk_update_type - trust radius update method ("step", "direction", "interpolation")
  - -tao_bqnk_as_type - active-set estimation method ("none", "bertsekas")
