Detailed Description

This class "preconditions" by identity matrix, but implements all other important routines, that can be used by derived classes, namely:

setup : Loads / computed radial integrals for construction of the matrix of the set and for the construction of the right-hand side.
update : Creates the diagonal blocks.
rhs : Composes the right-hand side.
multiply : Multiplies a vector by the matrix of the set of equations.
