Draft Model: better annotation with is / isHomologTo

[cb-Hades]

During the renaming of the genes in the draft model creation, it might be better to sort the available annotations to what truly can be considered an is relationship (default currently) and what would better be describes as isHomologTo using the bqbiol formulation of SBML.

• keep the old gene name or already covered using the NCBI protein reference? Does this work for all models or just the one tested?

Possible problem: current implementation of the function solely based on COBRApy
