  • added spai0
  • removed synonyme of ILU0 and ParallelOverLappingILU0 and intrudced ILU for dune 2.8

This smoothers may be valuable for smothers in amg of the pressure solve in cpr. ILU may also have advantages over standard block ilu if cpr if resort is not used.

Failing example since block size>1 not implemented:

{
    "tol": "0.01",
    "maxiter": "200",
    "verbosity": "3",
    "solver": "bicgstab",
    "preconditioner": {
        "type": "Spai0",
        "relaxation": "1",
        "repeats": "1",
	"left_precond": false,
        "verbose" : "3"
    }
