Add monmap

>> dso = add_monmap(dso,monitor_map_file)

This will add a monitor map file location to a data_source object:

• dso is a data_source object (class: IXTdata_source)
• monitor_map_file is a string defining the location of the monitor map file to be loaded, eg. 'X:\mapfiles\inst.map', or 'inst_maps:::myfile.map' (where inst_maps is a global path)
