Motivation

The list_problem_vars method on Problem is useful for giving a concise summary of all the driver variables (design variables, objective, constraints) at the end of an optimization. However, the values it prints are the scaled values that the optimizer sees. When using this as a summary, it would be useful to see the unscaled values.

Description

The easiest way to do this is to add the argument "scaled" to the call. If you set this to False, the values are printed unscaled. The default value is True, which prints the scaled value just like the current implementation.
