Mark Aron SzulyovszkyandGitHub b6cd6b14fe feat(Config): feature extractors are enabled one-by-one with a bool, added previous model to model.fit() (#77)
* feat(Config): feature extractors are enabled one-by-one with a bool, added previous model to model.fit()

* fix(Sweep): removed unused `other_features` parameter that fails sweep

* feat(Config): using preset names for defining feature extractors again

* fix(Tests): fixed model stub classes
