        Change the sign of the phases in all visibility columns

        Keyword arguments:
        vis -- Name of input visibility file
                default: none; example='3C273XC1.ms'
        spwlist -- Select spectral window
                default: [] all spws will be conjugated; example: spw=[1,2]
        outputvis -- name of output visibility file
                default: 'conjugated_'+vis; example= 'conjugated.ms'
        overwrite -- Overwrite the outputvis if it exists
                default=False; example: overwrite=True

        Example:

           conjugatevis(vis='NGC253.ms', spwlist=[0,1], outputvis='NGC253-conj.ms')

        Will conjugate all visibilities for spectral windows 0 and 1 and store the
        modified data in NGC253-conj.ms.
