Initialize the solver to an iterate, providing a complete state.
The CGIteration contains a certain amount of state, consisting of the current residual, preconditioned residual, and decent direction.
initialize() gives the user the opportunity to manually set these, although only the current unpreconditioned residual is required.

Get the current state of the linear solver.
The data is only valid if isInitialized() ==
