The state of the tagger including all resources is saved in a model file that can be passed to the constructor in future uses of the same model. The model requires the crfsuite model files to be in the same path with .crfs extension: <model_path>.crfs; A copy of the configuration is also pickled on training for ease of access.
Completed and tested model dumping functionality. Models are dumped into two files <mp> and <mp>.crfs. Having one file is possible, but would require writing the crfs model to disk and passing the path to the CRFS library. It could be improved if the library allows reading in-memory models.
