Extend HyTeG to work on level 1 and 0
Apparently for some P1 GMG tests (even P1-P1 Stokes) we can plug in level 1 as minimum level and it works. Level 0 could really be helpful to accelerate our coarse grid solvers.

indexing -

operator assembly -
single level solvers (CG, PETSc suite, ...) -
grid transfer, multigrid solvers -
fix 2D -
function iterator, PETSc field split indexing -
