-------------------------------

    Attachment: GIRAPH-68_2.patch

Avery,

Thank you for review.

I think that the GraphGenerator is necessary to test the overall of IO-related sub systems.
For example, *InputFormat and Partitioners can be examined by some generated data set instead
of PseudoRandomVertexInputFormat.

As you mentioned, I modified PageRank/RandomMessageBenchmark to use a specified InputFormat
and an input path. If the input format and input path are not given, they will work as the
current implementation using PseudoRandomVertexInputFormat.

> To provide users with benchmark environments and to deeply test the input/output system
of giraph, we need a graph generator. We will enable the graph generator to generate various
kinds of graph data sets by specifying a VertexInputFormat and a VertexOutputFormat.
