 ### MACAW: `dead_end_test`
 Looks for metabolites in Human-GEM that can only be produced by all reactions they participate in or only consumed, then identifies all reactions that are prevented from sustaining steady-state fluxes because of each of these dead-end metabolites. The simplest case of a dead-end metabolite is one that only participates in a single reaction. Also flags all reversible reactions that can only carry fluxes in a single direction because one of their metabolites can either only be consumed or only be produced by all other reactions it participates in.
