  ===========================
  +- Added AlgebraicCeedSolver that does matrix-free algebraic p-multigrid for
  + diffusion problems with the Ceed backend.

  - Added interface to MUMPS direct solver. Its usage is demonstrated in ex25p.
  See http://mumps.enseeiht.fr/ for more details. Supported versions >= 5.1.1.

  matrix with the function HypreParMatrixFromBlocks. This could be useful for
  solving block systems with parallel direct solvers such as STRUMPACK.

  -
  - Added CUDA support for SUNDIALS ODE integrators. See the updated SUNDIALS
  modification of Example 9/9p.
