Improve sparse usage (Jacobian, Hessian of the constraints) in the CTDirect package.

  • use problem information from ipopt after initialization to check if the NLP is solved with sparse or plain matrices (check number of nonzero elements in Jacobian and Hessian versus problem dimensions) and print a message.
  • check latest versions of the AD/NLP packages
  • benchmark
