If two models contradict each other (such as by each stating a initial
value for concentrations of the same species, or a different mechanism
for the exact same reaction), then this contradiction has to be fixed
before the models can be composed.
I am therefore focusing on clean ways to compose non-contradictory
models which involve some overlap of chemical species (and so the
assumption is that the initial values are the same).
