Shared files for working with signed graphs
Fixed bug in decoding of signed_code
Python file to translate adjacency lists to signed_code files.

The adjacency lists only need to list the neighbours with a larger index
Program to display signed graphs in signed_code format
Style correction: use boolean type where applicable
Fixed bug: the last argument of addEdge is not the sign, but a boolean telling whether the sign is negative
Conversion program for multi_code to signed_code
Fixed error message while reading multi_code
Fixed bug while reading multi_code

The string was ended at the wrong position
Program to give all signatures for given graphs in multi_code format
Removed debugging code left by accident
Version of signed_all for graphs with high symmetry
Increased maximum degree
Fixed spacing
Debugging method to print an edge set
Fixed bug: reset edge set counter for each graph
Added export to multi_code for signed graphs (signs are not exported)
Program to compute whether given signed graphs have a k-flow
Write a summary at the end of the program.
Made summary more informative
