Constructor.

Parameters

maxLevel	The maximum number of levels allowed in the matrix hierarchy (default: 100).
coarsenTarget	If the number of nodes in the matrix is below this threshold the coarsening will stop (default: 1000).
minCoarsenRate	If the coarsening rate falls below this threshold the coarsening will stop (default: 1.2)
prolongDamp	The damping factor to apply to the prolongated update (default: 1.6)
accumulate	Whether to accumulate the data onto fewer processors on coarser levels.
useFixedOrder	Flag indicating if creating indices for the coarser level should be done in a fixed order, i.e., the order in which the rows were sent. If set to true, this makes the runs reproducible but it might slow down performance.
