Add support for full paths to Data::set_station_coordinates
This adds the option to specify LAYOUT_DIR
as an environment variable when running the IDG example programs. One can either pass the name of a layout file (e.g. LOFAR_lba.txt
) in the IDG_DATA_DIR
prefix, or a full path to another layout (e.g. ~/my_telescope_layout.txt
). To support this, some no longer used data initialization functions had to be removed.
