Guido broke the charge conjugate plaquette action with premature optimisation.
...
This sector of the code does not matter for anything other than Guido's quenched HMC
studies, and any plaq specific optimisations should be retained in a private branch
instead of destroying the code simplicity.

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

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.

Also works for nested templates. I find it useful for debugging.
Possible usage:

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