The Scenario Load Group includes all of the major scenario-related data tables.

Reference to a hash of command-line options.

=item tables

List of tables in this load group.

    $sl->Connect($mapID, $fileName, $relName, $method);

Create the relationship records connecting the specified map to the

columns containing the rectangle coordinates of the compound or reaction
in the diagram.

ID of the relevant map.

Name of the file containing the coordinate data.

Name of the relationship to be filled from the data.
