DEV_NOTES

@@ -3 +3 @@
  - move more of "mogi" to mystic.models
 mystic/mystic/scipy_optimize.py:
- - better way to deal with direc, maxfun, maxiter (?)
+ - better way to deal with direc (?)
 mystic/mystic/differential_evolution.py:
  - use wrap_bounds instead of existing method (?)
  - fix bug: DESolver throws error when given numpy.inf as a bound (!)
- - enable signal_handler & sigint_callback (?) for all 'one-liner' interfaces
+ - resolve strategy, CrossProbability, & ScalingFactor against AbstractSolver
+ - allow register of sigint_callback for all 'one-liner' interfaces (?)
  - DESolver needs documentation

DEV_TODO

@@ -5 +5 @@
 * Update the parallel branch (pyina), get "handler" to work in parallel (ipd?)
 * Better 'programmatic' interface for handler
+* Add more options to handler (i.e. toggle_verbosity?, get_cost?, ...?)
 * Allow sigint_callback to take a list (i.e. provide call[i])
 * Add "constraints" to models (design similar to pyre.inventory and validators)
