#8 Make Parse and Span serializable

[Anonymous]

I wonder if you could make opennlp.tools.parser.Parse and opennlp.tools.util.Span serializable by implementing the Serializable interface on both classes.
This would make caching of expensive parsing operations easier.

Never worked with java serialization before, would it be enough to simply implement the marker interface on both of the classes ?
