what part of parg[igCLhCGfwd] don't you understand

Readable names are useful for transferring results to the outside world, esp. via IO functionalities (i.e., column headers in output_csv or as part of the human-readable toml outputs). We need a readable name for all par_array variables.

It's easy to work piecemeal on this. Ask @aditeyashukla or @argonaut22 for directions to the translation spreadsheet/style guide.
