Hi,

Should be make a generic solver base class:

class Solver {

    virtual uint solve(const GenericMatrix& A, GenericVector& x, const GenericVector& b) = 0;

};

The class LinearSolver is using Matrix and Vector now, and I think it should
be safe to change this to a more generic interface. Alternatively, the Solver
class could be named:

GenericLinearSolver
LinearSolver
GenericSolver

Similarly, we could have GenericPreconditioner:

class GenericPreconditioner {
    virtual void update(const GenericMatrix& A) = 0;
    virtual void apply(GenericVector& x, const GenericVector& b) const = 0;
};

Implementing these interfaces in DOLFIN should be simple; simply add the
methods and use dynamic_cast to call existing functionality.
