Import methods in result.py now return a vector containing the names of the imported quantities.
SB model building cycle implementation - 'scripts' folder created; added data files and drafts for solver comparison, artificial data generation and parameter estimation steps.
Cleaned scripts for steps 1 and 3; artificial data generation can be more finely parameterized (type of noise, observables).
Parameter estimation script cleaned and made more generic.
Deleted unused FEBS_copasi.xml SBML file
