       graphs are structures, built of nodes, archs, and cross-roads.
       helps mapping, organizing and modelizing data.
       directed or un-directed.
       graphs examples:
       navigation 
       communication
       data - find fastest way using routers.
       requires:
       table of nodes against nodes:
       diagoanl is nulled, as node won't point itself.
       at first all is nulled, but get a value if a connection is
       established.
       or
       
       adjasting list - buckets:
       for every node a list of connections.
       exact size, but takes more time to handle than table does.
