USAGE

        color_obj(rainbow=0, cnc=0)

ARGUMENTS

        rainbow = integer: 0 to use the 22 named colors, or 1 to generate
        a rainbow based on the number of objects currently

        cnc = integer: 0 to color all atoms by object, 1 to color non-carbon
        atoms according to their element.

NOTES
        This function colours each object currently in the PyMOL heirarchy
        with a different colour.  Colours used are either the 22 named
        colours used by PyMOL (in which case the 23rd object, if it exists,
        gets the same colour as the first), or are the colours of the rainbow

        If cnc is set, color non-carbon atoms by their element
