Tipset graph generator (low priority)

A lot of the current tests and benchmarks use a random graph generator for generating events. Benchmarks could show different results for graphs that are generated by production code. We need a graph generator that uses the tipset algorithm to generate graphs. Extending the existing GeneratorEventGraphSource so that it can use the tipset algorithm would be ideal. Once this extension is ready, the consensus benchmark should be run with the new graph to compare the measurments.

Start by locating GeneratorEventGraphSource and the consensus benchmark code. Read how the existing random event graphs are generated, then trace the tipset algorithm used by production code. Done means the generator can produce tipset-based graphs and the consensus benchmark has been run to compare its measurements with the existing graphs.
