* \brief An algebraic twolevel or multigrid approach for solving blackoil (supports CPR with and without AMG)
*
* This preconditioner first decouples the component used for coarsening using a simple scaling
* approach (e.g. Scheichl, Masson 2013,\see scaleMatrixDRS). Then it constructs the first
* coarse level system, either by simply extracting the coupling between the components at COMPONENT_INDEX
* in the matrix blocks or by extracting them and applying aggregation to them directly. This coarse level
* approach (e.g. Scheichl, Masson 2013,\see scaleMatrixDRS). Then it constructs the
* coarse level system. The coupling is defined by the weights corresponding to the element located at
* (COMPONENT_INDEX, VARIABLE_INDEX) in the block matrix. Then the coarse level system is constructed
* either by extracting these elements, or by applying aggregation to them directly. This coarse level
* can be solved either by AMG or by ILU. The preconditioner is configured using CPRParameter.
* \tparam O The type of the operator (encapsulating a BCRSMatrix).
* \tparam S The type of the smoother.
* \tparam C The type of coarsening criterion to use.
* \tparam P The type of the class describing the parallelization.
* \tparam COMPONENT_INDEX The index of the component to use for coarsening (usually the pressure).
* \tparam COMPONENT_INDEX The index of the component to use for coarsening (usually water).
* \tparam VARIABLE_INDEX The index of the variable to use for coarsening (usually pressure).
