====== Description of networks ======

  -	types of networks (ordinary, two-mode, multi-relational, temporal, collections and sequences) and their description
  -	additional data structures (vectors, partitions, permutations, hierarchies, ...)
  -	libraries to work with networks (NetworkX, igraph, snap, NetworKit, ...)
  -	data formats (pajek, json, graphML, ...)
  -	existing network data  bases; input and output routines
  -	special descriptions: molecules, GED, ...; examples
  -	degrees, fitting, Erdos-Renyi networks, scale-free networks, Dunbar number, large networks
  -	try it yourself; summary

  * list of links
  * list/dictionary of lists/dictionaries of neighbors  (isolated nodes, parallel links, weights, properties; topology, sorted) efficiency of operations, space requirements/consumption
  * multi-relational (multiplex), two-mode, temporal
  * operations: fis - first in second table - union, intersection
