feature: added tolerance criterion to ProximalPoint and ProximalGradient #176

This PR introduces a stopping criterion to ProximalPoint and ProximalGradient based on the change in objective function between two consecutive iterations.

Ultimately the same criterion must be implemented on all solvers.
