        DataStore createDataStore​(Map<String,​?> params)
                           throws IOException
        Construct a live data source using the params specifed.

        You can think of this as setting up a connection to the back end data source.

        Magic Params: the following params are magic and are honoured by convention by the GeoServer and uDig application.

        • "user": is taken to be the user name
        • "passwd": is taken to be the password
        • "namespace": is taken to be the namespace prefix (and will be kept in sync with GeoServer namespace management.
        When we eventually move over to the use of OpperationalParam we will have to find someway to codify this convention.
