WilsonMG: Comment assertion on hermiticity of coarse operator for now 
TODO: Think of a way to not break dwf_hdcr by doing that. It's only an assertion
but it still interferes with it.

Add first version of multigrid for wilson clover analogous to wilson one 
Just like the wilson one, this algorithm

• is currently only a 2-level method since I don't have correct implementations
  for Mdir and Mdiag in CoarsenedMatrix yet (needed for further coarsening)
• needs levelization and refactoring into a proper algorithm

Fix bugs in Flexible GMRES solvers 
Somehow I got the left and right-preconditioned versions of GMRES mixed up. As
of now this is right-preconditioned version, which is what we want.

WilsonMG: Some further steps towards a three level method 
Currently this is very "manual" as we are still testing stuff. Will refactor
and make it an algorithm once everything works.

What currently does work:

  - All tests in MultiGridPreconditioner::runChecks for the first coarse grid
  - The tests for the intergrid operators going from the first to the second
    coarse grid
    - (1 - P R) v   == 0
    - (1 - R P) v_c == 0
  - A full solve with VPGCR and a two-level MG preconditioner

What hinders the rest of the tests from passing with a three-level method is the
absence of implementations of CoarsenedMatrix::Mdir and CoarsenedMatrix::Mdiag.

Add function to return full type as std::string 
Also works for nested templates. I find it useful for debugging.
Possible usage:

std::cout << "getTypename<AType>() = " << getTypename<Atype>() << std::endl;
std::cout << "getTypename<decltype(AnInstance)>() = " << getTypename<decltype(AnInstance)>() << std::endl;
