v0.1.2

This release makes enzax's interface more extendable, easier to work with and potentially allows for both models whose fluxes come from structured and tested rate equations and also models that generate fluxes arbitrarily, hopefully including in future from symbolic expressions parsed from SBML. Some day we will have our cake and eat it!

In the meantime enzax is still an early work in progress and likely to chage: please don't rely on it yet!
