dyssco.py

changed "get_dfba_solution" flag to "save_dfba_solution"
added abstract methods:
calculate_titer_from_dfba()
calculate_productivity_from_dfba()
added choice to use bioreactor-specific methods for calculating titer and productivity.
- calculate_titer_from_dfba()
- calculate_productivity_from_dfba()
