NotSerializableException

[Google Code Exporter]

When I set the "-save-model" option, I got java.io.NotSerializableException:
    at depparsing.io.DepProbWriter.writeToFile(DepProbWriter.java:16)
    at depparsing.programs.RunModel.parseCommandLineArguments(RunModel.java:225)
    at depparsing.programs.RunModel.main(RunModel.java:187)

It turns out that in the class DepProbMatrix, two member variables, DepCorpus 
corpus and NonterminalMap nontermMap, are not serializable.
