1.0 (2014-01-02)

• Adding the --max-categories option to handle datasets with a high number of categories.
• Adding the --method combine option to produce predictions with the sets of datasets generated using --max-categories option.
• Fixing problem with --max-categories when the categorical field is not a preferred field of the dataset.
• Changing the --datasets option behaviour: it points to a file where dataset ids are stored, one per line, and now it reads all of them to be used in model and ensemble creation.
