Description: fixes problem reported in #434 and extends #179. move to __call__ as primary frequency response method to be used in TransferFunction, StateSpace, and FrequencyResponseData systems. (__call__ is new for StateSpace, and FrequencyResponse) the new __call__ has same interface for all three classes, and can now take one or an array of s, unlike the old _evalfr, which could only take one s it also adds a convenient keyword argument squeeze=True that automatically squeezes output if sys is SISO for FrequencyResponseData.__call__(s), s must be purely imaginary or an error is raised private method _evalfr that was inconsistent with matlab module matlab.evalfr was removed in favor of __call__ method sys.evalfr(s) has been deprecated for 2.5 years and is now removed. use __call__ instead, or matlab.evalfr(sys, s) (following discussion in #434) method sys.freqresp(omega) is now deprecated. Use new pythonic methodsys.frequency_respose instead, or freqresp(sys, omega) from matlab module (following discussion in #434) horner(s) now does the same thing for both TransferFunction and StateSpace systems: can evaluate at multiple values of s de-duplication of code, cleanup, pythonization and vectorization of code where possible FRD.eval behavior was left as-is, except for an optional squeeze argument
