        Tests that a class has a static factory method getInstance() and that it acts as a singleton. NB This method will create an instance of the class. It is your responsibility to clean up after yourself.
        Parameters:
        c - the class to test
        Returns:
        the singleton

        Tests if there are any public constructors. Will fail on any public constructor, and simply return otherwise.
        Parameters:
        c - A class to test.

                                     java.util.List excludedFields)
                              throws java.lang.IllegalAccessException
