Detailed Description
template<typename T>
class Chroma::SystemSolver< T >
Linear system solvers.
Solves linear systems of equations. The solver may only live on a subset.

◆ operator()()

Apply the operator onto a source std::vector.
Solves A*psi = chi or psi = A^(-1)*chi up to some accuracy. There is the interesting possibility of generalizing to support PLUS/MINUS
Should the accuracy be specified here ???
