- add fudge mode which gives a slightly slower hash function, but works
almost always in the first iteration by avoiding degenerate edges
- avoid keeping incidence lists around reducing the memory foot print by
30%
- split edge processing from hashing as in the non-fudge case it is a
reasonable costly part that often gets thrown away
- merge graph2 and graph3 routines now that they are mostly the same
Implemented are the 3-graph BDZ algorithm as well as the
2-graph and 3-graph CHM algorithms. All algorithms have expected
linear run time and the smallest functions need around 2.85 bit/key.
