Fixes #12 .
Fixed issue by changing the possible values of the FeatureOperation encoder attribute from EncodingFunctions.ONEHOT/ORDINAL class to EncodingFunctions.ONEHOT.value() instance.
Infact the encoder attribute is meant to store the actual instance of one of the classes listed in EncodingFunctions Enum.
Changed FeatureOperation __eq__ method accordingly.
Added a check in FeatureOperation constructor in order to validate the encoder argument.
