docs: Given an edge (`vertex0_id`, `vertex1_id`) from a
          different CoNetwork, return the corresponding edge id from this
          CoNetwork (`self`).
  
          Parameters
          -----------
          vertex_id_conversion : dict (int -> int)
            the dict produced by `convert_pathway_mapping,` which maps
            the other CoNetwork's vertex ids to this CoNetwork's vertex ids.
          other_edge_id : tup(int, int)
            the edge id for the edge in the other CoNetwork
  
          Returns
          -----------
          tup(int, int), the corresponding edge id
