Daniel Richtmann f20728baa9 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.

Daniel Richtmann d2e68c4355 WilsonMG: Perform some minor cleanup 2018-01-29 18:07:10 +01:00
Daniel Richtmann 1cb745c8dc 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;

and an include in the algorithms header file.
