void BuildCoarseGrid(Level &fineLevel, Level &coarseLevel) const
void DeclareInput(Level &fineLevel, Level &coarseLevel) const
Specifies the data that this class needs, and the factories that generate that data.
void Build(Level &fineLevel, Level &coarseLevel) const
Build an object with this factory.
