Will Pazner f31b3d03da Attempt to future-proof BlockILU interface 
Added a parameter for reordering method. Currently it is only possibly
to specify MDF or none, but it should be possible to add e.g. minimum
degree ordering fairly easily.

Also added a parameter k for ILU(k), but only k=0 is supported.
