Kinetic Law autocompletion

[anandijain]

I like what we have so far, hooking into RHEA.

The next step, which I'll want your help figuring out is:
http://www.ebi.ac.uk/sbo/main/SBO:0000268 check the children nodes.

basically we assume that we know what the reactants and products of a reaction are (from an SBML model, or specified manually), we then want to use informtion about the species to figure out which class of rate law (in the SBO) the reaction falls inot.
