Rather than rewrite an existing test to be complex, better to add a new test and leave the old test in place.

Why comment this out? This will probably cause unit tests to fail when slycot is not installed.

PR to start to rewrite tests with complex matrices (issue #371) in a new branch. So far it seems that poles and zeros are calculated OK, but adding/subtracting/multiplying systems fails.
I've also commented out some "skip if slycot not installed"; some of these tests nonetheless run with sylicot uninstalled
