Reverse import of OLI model in Aspen Plus

There is a certain order of workflow to follow when one imports an Aspen Simulation in an OLI model bkp file.

Currently this is t he only supported way of working OLI inside of Aspen.

If user accidently creates a simulation file first and then tries to import the chmeistry model, at the final step of simulation run, user will see the following error message.

Please note that this message means that Aspen is unable to read the OLI chemistry model.
