Function harmonization

[albop]

WIP

All main solution algorithm should take the same kind of arguments

1. time_iteration
2. impoved_time_iteration
3. value_iteration
4. steady_state
5. deterministic_solve
6. perturbation.perturb
7. perturbation_higher_order.perturb

In particular, they should have the same name when they have exactly the same interpretation.

• model: Model
• dr0: DecisionRule # initial decision rule
• ignore_complementarities=False: Bool # ignore complementerities in euler equations
• verbose:
  • false: print nothing
  • true: print only the outer loop
  • 'full': print info on outer and inner loops
• details=True Bool # whether to return details about optimization or the decision rule
• trace:
  • false: don't save iteration results
  • true: save only iteration statistics
  • 'full': save iteration statistics and itermediate decision rules
• dprocess:
  • none: use default options to discretize
  • discretized process
• hook: Fun # external function called at the beginning of each iteration.
• interp_method="cubic"
