Enable rule-based modelling (like in BioNetGen)

[TorkelE]

BioNetGen, and possibly some other tools, allows rule-based modelling. In certain cases this enables you to create a rather large network from simple rules

E.g. a molecule with 4 binding sites to which stuff binds independently, you have many different reactions and states that could all be defined by the binding rules for the independent sites.

Not sure when we would actually be able to add this, but it seems nice to add it to the list of potential additions. Coming up with an interface could be a partial step.
