/*MC
  TAOBQNKTL - Bounded Quasi-Newton-Krylov Trust-region with Line-search fallback, 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")
