simplify optimizers #606

Open lukasheinrich opened 4 years ago

lukasheinrich commented 4 years ago

Description

it's probably a good idea to constrain our optimizers to the sole problem of doing unconstrained optimization. a possible API could be

objective = pyhf.create_objective(model, fitconfig)                                                                                                                                                           
bestfit = pyhf.optim.optimize(objective)

@lukasheinrich When we talked today you had a bit of a vision for what would need to get done to have a proper Infer module. Can you also comment here a bit and give a brief "Road to Infer"?
