        """View a visibility data set

        examples of usage:

        msview
        msview "mymeasurementset.ms"
        msview "myrestorefile.rstr"
        
        Keyword arguments:
        infile -- Name of file to visualize
                default: ''
                example: infile='my.ms'
                If no infile is specified the Load Data window
                will appear for selecting data.
        displaytype -- (optional): method of rendering data
                visually (raster, contour, vector or marker).  
                You can also set this parameter to 'lel' and
                provide an lel expression for infile (advanced).
                default: 'raster'

        Note: there is no longer a filetype parameter; typing of
        data files is now done automatically.
                example:  msview infile='my.ms'
                obsolete: msview infile='my.ms', filetype='ms'
