FirstOrderMinimizer to optimize on f(x) and proximal operator
A subset of proximal operators can be represented as Projection operators and for those operators, we give an option to the user to choose a projection based algorithm. The options available for users are SPG (Spectral Projected Gradient) and PQN (Projected Quasi Newton)
