Good to see that the linear algebra is coming along. Some comments:

- solve() should be static to enable NewGMRES::solve(), same as
  GMRES::solve().

- There should be a version of solve() that can handle VirtualMatrix.
  I think the code will be the same, just call VirtualMatrix::mat().

- We need to add a class NewPreconditioner that can be passed as an
  argument to NewGMRES, something like

class Preconditioner
{
    virtual void solve(NewVector& x, const NewVector& b) = 0;
}

class MyPreconditioner : public Preconditioner
{
    void solve(NewVector& x, const NewVector& b);
}

MyPreconditioner pc;
NewGMRES::solve(A, x, b, pc);
