Engine: Find the tangent space of the solution variety

Browse source 
At the end of the realization routine, use the computed Hessian to find
the tangent space of the solution variety, and return it alongside the
realization. Since altering the constraints can change the tangent space
without changing the solution, we compute the tangent space even when
the guess passed to the realization routine is already a solution.
