A class to construct a ModelMessage from a PerceptronModel instance.
TODO(dbikel): Need some kind of a factory for model writers, so the proper ModelProtoWriter gets instantiated given a particular Model subclass.

Serializes a PerceptronModel instance to a ModelMessage.
When the write_features parameter is true, the feature vectors written out will be those of the best model epoch (typically the epoch with the lowest average devtest loss).
| model | the PerceptronModel to be serialized to the specified ModelMessage |
| model_message | the ModelMessage to be filled in by this method with the serialized version of the specified Model |
| write_features | whether the features of the specified Model should be written out |

Writes out the features of this model to a series of FeatureMessage instances using the specified ConfusionProtoIO instance.
This method writes out both the raw feature values as well as the averaged values; however, the averaged values are stored in the avg_value field of the FeatureMessage object. In contrast to the behavior of the Write method, the features written out by this method will be those of the current model, as opposed to those of the best model.
| model | the PerceptronModel to be serialized to the specified ModelMessage |
| os | the output stream to which to write features |
| output_best_epoch | output the weights of the best epoch of training, as opposed to the most recent epoch |
| weight | the weight by which all feature weights should be multiplied before being output |
| output_key | output the key (feature name) and separator for each feature |
| separator | the separator string to output between each feature’s key and its base64-encoded FeatureMessage (only used if output_key == True) |
