networkname.tar.gz contains two files: networkname.functions and networkname.matrix

networkname.functions:
contains names of nodes (webpages or functions).
First line states the number of nodes (from 0 to N-1).
Then the notation is the following:
# node number -> node name
#  | outgoing node name -> outgoing node number

networkname.matrix:
contains information of S matrix (normalized Adjacency matrix w/ avoided dangling nodes).
Each line of the file represents a link of the network written in three columns:
link goes from first number node to second number node with weight given by third column.
When first and second column are the same and third column is -1 means a dangling node,
and we have to put N links from this nodes to all nodes with weight 1/N
