Solvers output

[vepiteski]

Distinguish failures from

• unsuitable models (for instance with constraints for an unconstrained solver)
• erroneous models (for instance, f(x_0) fails)
• etc.

More generally, devise a sound output format including the solution, statistics of computation, status (property of the returned solution).

The ExecutionStats here should be it, but it doesn't handle every possible case. Also see #90.
