1) fixed a bug in bidirected_inc - it is working now correctly
(debugged against ecj.undersample
2) added undersample function, compared to ecj it runs from 1 to
several orders of magnitude faster depending on the size and density
of a graph
added check if g2 is a superclique already
Printing simple loops is now sorted by length
renamed eqc function to g22g1
renamed eqc to g22g1 (as in traversal.py module) and set CAPSIZE as a parameter
started using CAPSIZE and also moved REPEATS parameter up the file
playing with a different file
