Simulation fails from imported model that is serialized with gillespy

[ahellander]

The follwing fails:

1. Export a model using model.serialize() and write to file.
2. Import the model
3. run the imported model.

The reason seems to be that the exported file contains a parameter "vol" with value 1. StochKit2 does not seem to like that, for reasons I don't know. Removing that parameter from the xml file removes the error.

Does it think "vol" is another parameter and tries to multiply define it when it's serialized again for StochKit2? Can the exported model be run without re-importing it?
