Test for eflux3 fails right now, working on clarifying the test.

Some assumptions about the workflow:

• User has the cobra model they want in the form they want (removed reactions, objective value set, etc.)

either:

• User provides transcriptomics data that matches the gene names listed in the cobra model as a dataframe such that the column containing the transcript label set as the index.
  or
• User provides proteomics data that matches the bigg reaction name in the cobra model as a dataframe such that the column Reaction_ID set as the index.
