APREPRO: Allow opening multiple exodus files #757
Description
Currently the exodus metadata functions in aprepro create variables of the form ex_XYZ.
If you rerun this with a different exodus file, the ex_XYZ variables would be overwritten.
There should be an option that will specify the prefix name that is used for the exodus metadata variables. There could then be multiple uses of the exodus metadata functions and they would each define their own set of aprepro variables.
