        Call a GMT module with the given arguments.
    
        Makes a call to ``GMT_Call_Module`` from the C API using mode
        ``GMT_MODULE_CMD`` (arguments passed as a single string).
    
        Most interactions with the C API are done through this function.
    
        Parameters
        ----------
        module : str
            Module name (``'coast'``, ``'basemap'``, etc).

        Raises
        ------
        GMTCLibError
