Description

Desired capability or behavior.

We should investigate replacing the custom json file that is created to save the results of a design mission (used to "re-load" the problem for off-design) with a csv file using the new utility for that.

Suggested implementation.

Aviary should always produce a csv file with the post-optimization values for all OpenMDAO variables in the variable hierarchy as well as all options in the hierarchy. This can be re-used for off-design runs. The json file format currently only saves variables that were originally specified in the input file, and isn't capturing changes in those values which is important for design variables. We still need to solve that problem for this new format.
