Detailed Description

Structure to manage the lifetime of MFEM solver objects.

This structure ensures that the mfem::GMRESSolver outlives the mfem::NewtonSolver that might use it. The mfem::NewtonSolver often takes a pointer or reference to a linear solver, and if the linear solver is destroyed first, it can lead to dangling pointers and crashes.

Note: The order of declaration of members is crucial: solver must be declared before newton to ensure it is constructed first and destroyed last.
