The regression report had an issue when I added the deciles output to the report for the classification case. That's been fixed.
For the create_model_data function, RetroFit will no longer throw an error if you pass a single string variable name to either NumericColumnNames, CategoricalColumnNames, or TextColumnNames. Additionally, if a user passes a list to TargetColumnName (e.g. ["TargetVar"], there will no downstream errors.
