Function to_dist_geo_layer 

pub fn to_dist_geo_layer(net: &MulticonductorNetwork) -> GeoLayer

Transform legacy bus drawing positions and line routes to a geographic layer. Component geography (component_locations) is a separate typed table: partial axes, unknown datums and arbitrary device attachments cannot be expressed by this legacy layer. Use to_dist_geo_layer_report when extracting a network that may contain that table.
