v1.2.0

• Improvements on supervised_image_stream_reader
• Model schema is now stord in Protobuf format. Use convert_schema to convert schemas in old binary format to new one
• Input and output data normalizers are stored in protobuf format now. Use convert_input_normalizer and convert_output_normalizer to convert existing binary normalizers to new format
• Nesterov momentum added (see --momentum_type option)
• ROC result outputs accuracy, precision, recall, and F-score now (in addition to AUC)
• snapshot_invalid now saves images, including binary classifier case
• uniform_intensity_data_transformer added
• Momentum data is kept between epochs (it is save and restored as well)
• embed_data_transformer added
• Schema and data are compatible now if non-empty layers match. Now empty-data layers don't matter
• Overfeat functionality added (see tiling option of max subsampling layer, and untile layer)
