Bug when SBML network having reactions without lists of reactants or products
Some SBML networks have some reactions without lists of reactants or lists of products, in particular for external reactions. For example, the E. coli core SBML network (presents in BIGG) have this type of reactions. These absent lists cause errors of the type:
File "<path_to_precursor>/precursor/src/sbml.py", line 165, in readSBMLnetwork
for p in listOfProducts:
TypeError: 'NoneType' object is not iterable
