Description: This PR addresses issue #453 by implementing a uniform method for handling the squeeze keyword in frequency response functions (frequency_response, __call__, etc). This PR matches the changes in PR #511 to improve consistency between time and frequency response, as described in issue #453. The following behavior is implemented: squeeze=None (default case): squeeze inputs and outputs, but leave frequencies alone. This is consistent with current behavior. squeeze=True: numpy squeeze => all singleton axes are removed, consistent with numpy. squeeze=False: full MIMO, even for SISO. You always get a p x m array for outputs versus inputs. Additional changes: A new global default control.squeeze_frequency_response that sets the default value for the squeeze keyword (set to None initially). Passing a set of frequencies (or complex values) that is not a scalar of a 1D array_like generates a ValueError exception. Updated docstrings Unit tests to make sure that all of the various cases for squeeze are correct. Some minor PEP8 cleanup along the way
