class  CIterativeShiftedLinearFamilySolver< T, ST >
abstract template base for CG based solvers to the solution of shifted linear systems of the form $$(A+\sigma)x=b$$ for several values of $$\sigma$$ simultaneously, using only as many matrix-vector operations as the solution of a single system requires. This class adds another interface to the basic iterative linear solver that takes the shifts, $$\sigma$$, and also weights, $$\alpha$$, and returns the summation $$\sum_{i} \alpha_{i}x_{i}$$, where $$x_{i}$$ is the solution of the system $$(A+\sigma_{i})x_{i}=b$$.
