Multiple changes, including new parameters for polymer injection and solvers.

Browse Source 
- "poly_start_days", "poly_end_days", "poly_amount" controls injection
   time interval and concentration of injected polymer.
 - Made a small class (PolymerInflow) for this control.
 - Now warns if polymer injection rate changes during timestep.
 - Parameters "nl_tolerance" and "nl_maxiter" control nonlinear scalar solvers.
 - Catch up to change in TransportModelPolymer (constructor args).
