Hello @cshenry !

Here are edits and error corrections for MSEditorAPI:

1. unused arguments are flagged
   

2. error messages were clarified
   

3. the catch of an unrecognized cpd ID was relocated to the beginning of the edit_biomass_compound function to remove redundancy and prevent unnecessary computation
   

4. items() is leveraged to greater efficiency
   

5. inconsistent reaction directionality (from my internship last summer) is replaced with consistent "<" & "=" symbols
   

6. default values were initially defined, instead of being defined in an else clause
   

7. in-line Metabolite definition is employed
   

8. my old prompts for correcting errors were removed for irrelevance
   

9. the solicitation for the clean_ends function to leverage strip() was fulfilled
   

10. list comprehension is employed
    

11. redundancy in the conditionals of get_coef_and_group() are eliminated by moving the error catch to the else clause
    

12. reactant is renamed to reagent since the function is used for both reactants and products, and thus the term reactant is a misnomer
    

13. the conditonals for directionality is simplified to a linear if..elif..else sequence and with consistent directional symbols
    

14. the erroneous construction of the reagents dictionary (variables in the old code) is corrected and consolidated
    

Thank you for your review :)
