Fix 214 #230

Closed tBuLi closed 5 years ago

tBuLi commented 5 years ago

Fixed #214. Variables are no longer set to None by default, all variables now need to be provided explicitly with data or None, unless Fit can infer from the data, model and objective provided that some should be ignored. This way debugging will be greatly improved, since currently it is still allowed to forget to provide data which causes a lot of pain when debugging.

Only important API change: None has to be provided explicitly to Fit when no data is present for a variable.
